John opened a new bank account and deposited a $215 check. Then he made a few withdraws of $40, $20, and $75 before he deposited one more check for $185.
**How much is now in John’s bank account?**

$109

$400

$128

$265

215 + (−40) + (−75) + (−20) + 185

= 400 + (−135) = 265

Therefore, John has $265 in his account.

**On every sale she makes, Maria earns a commission. On a computer that she sells for $591, Maria earns a $43 commission. Find the percent commission, rounded to the nearest tenth of a percent.**

7.3%

5.28%

7%

5%

Commission is what percent of sales price

43=591p

To isolate an unknown value p, divide both sides by 591. Carry the division to four decimal places.

Because the test digit is greater than or equal to 5, add 1 to the rounding digit, then truncate. Thus, correct to the nearest tenth of a percent,

Diver number one dives down 25 feet below sea level. Diver number two then goes down five (5) times further than diver number one.
**What is the final depth of diver number two?**

30 feet below sea

100 feet below sea

125 feet below sea

50 feet below sea

−25(5) = −125

The second diver’s final depth is −125 feet, or, 125 feet below sea level.

John’s bank is overdrawn. After he makes a $120 deposit, John sees that his account still is overdrawn by $75.
**So what was John's balance before making his deposit?**

the original balance was overdrawn by $205

the original balance was overdrawn by $195

the original balance was overdrawn by $250

the original balance was overdrawn by $155

Original Balance+ John Deposit=Current Balance

B + $120 = −$75

To isolate un unknown value B, subtract 120 from both sides.

B+120-120=-75-120

Simplify both sides.

B=-195

Answer the Question. The original balance was overdrawn to the tune of $195.

**Which of the following equations is written in slope-intercept form?**

9xy = 1

9y +1 = x

x - 9 = y

y = 9x - 1

A stationary store sells staplers for $1.50 each. A company buys an unknown number of these staplers at a cost of $36.00 in total.
**How many staplers did the company purchase?**

38

24

21

42

Set Up an Equation.

1.50N = 36.00

To isolate an unknown value N, divide both sides of the equation by 1.50.

The business purchased 24 staplers.

The diameter of one bicycle tire is 32 inches, and its spokes run from the hub (or center) to the edge of the rim. The diameter of another bicycle wheel is 24 inches.
**What is the difference in inches between the length of the spokes of the two wheels?**

12

4

8

6

Therefore, the spoke for the 32-inch wheel is 16 inches.

The spoke for the 24-inch wheel is 12 inches.

16 - 12 = 4-inch difference between the two spokes.

**The number −6 is 2 more than an unknown number. Find the unknown number.**

-8

8

-6

6

-6 is 2 more than an unknown number

-6 = 2 + x

To isolate x, subtract 2 from both sides.

- 6 - 2 = x

Simplify both sides.

-8 = x

The unknown number is -8.

**Solve the equation**:

**Find the volume of a 15-inch hollow cylinder if its circular cross-section is as shown in the figure.**

Small radius: r = 2 u00F7 2 = 1. The green area (the base) can be computed by subtracting the area of the small circle from the area of the big circle. Big area, .

Small area, . Solving for the green area, A = 3.06π - 1π = 2.06π. Solving for the volume of the cylinder, V = 2.06π u00D7 15

**Which of the following equations define the line graph shown?**

Determine the equation of the line using the general format of , where b is the value of y when x is zero.

Solve for

*b*by plugging in either point. Let's plug in (3, 5):

Plugging all known values into the general equation of a line, you get:

This isn't an option, but if you clear the fractions by multiplying both sides of the equation by 2, you'll get:

2y=-3x+19

If you're not familiar with linear equations and how they are graphed, or don't have the time to do the computations, you may still get the correct answer by eliminating unlikely answers. Eliminate all choices with variables in the second degree (or higher) because linear equations are first-degree equations, meaning variables are raised to the first power only. Lines that slant upwards from left to right have positive slopes, while lines that take a downward slant from left to right have negative slopes. This line obviously has a negative slope. Eliminate all answer choices with a positive slope. If you know these basic things about a line and its graph, you may actually solve this type of question by simply inspecting the graph and the given answer choices.

**On the given number line, what is the value of A?**

**Which of the choices is represented by the given graph?**

and the points (0, b) and (8, 3).

Finally, we plug these values into the equation of the line following the format, y=mx+b

This is the equation of the line. However, the shaded area shows the inequality or values of y which lie on or below (equal or less than) the defined line. Thus, the linear inequality is correctly represented by TIP: Save time by realizing the shaded part is below the line, clearly indicating a "less than" inequality. There are two options, but one isn't in slope-intercept form. Once you turn it into this form, it is no longer a "less than" inequality.
