The circle graph below shows the results of a survey taken of people who want a career working with animals.

If 400 people were surveyed, how many people chose to be animal trainers?

- 36
- 40
- 45
- 360
- 364

**Answer:** 36

x = 400 × 9%

x = 400 × 0.09 = 400 × 9/100 = 36

A survey on popular ice cream flavors in a school cafeteria is displayed in the bar graph.

Which percent of students chose flavors in the top 2 categories?

- 25%
- 35%
- 50%
- 55%
- 60%

**Answer:** 50%

The number of students who chose chocolate and chocolate chip was divided by the total number of students in the survey.

20 + 5 + 26 + 23 + 13 + 20 = 107

Top 2 flavors

26 + 23 = 49

49/107 ≈ 50%, slightly less than half the students chose chocolate or chocolate chip.

In Canada, the cost of producing electricity accounted for 30% of all energy costs in a single year. How much was spent on the production of power if $30 billion was spent on energy?

One pen costs $0.25, and one marker costs $0.35. What is the total cost of 18 pens and 100 markers at those prices?

$0.25 * 18 = $4.5 + $0.35 * 100 = $39.5

A jar containing 60 hard candies comes in 22 black, 18 blue, 11 orange, 5 maroon, and 4 violet hues. Consider that only one hard candy needs to be selected at random. The likelihood that the candy won't be either maroon or violet would then be what?

- 0.09
- 0.15
- 0.54
- 0.85
- 0.91

**Answer:** 0.85

There are 4 violet candies and 5 maroons, 51 of which were neither violet nor maroon. The probability of selecting one of these is 51 out of 60. 51/60 = 0.85.

What is the value of x if 8x+64 = 8-6x?

- -4
- -56
- 12
- 7
- 4

**Answer:** -4

Thus, the following step is 8x+6x = -64+8. The subsequent step is, therefore, 14x = -56 and x = -4. Thus, the correct response is a) -4.

When 3x2 + tx- 21 = (3x - 3)(x + 7) what is the value of t?

- 18
- -3
- 21
- 24
- 18

**Answer:** 18

Use the method of FOIL (First, Outside, Inside, Last):

(3x - 3) (x + 7) = 3x2 +21x - 3x - 21 = 3x2 +18x -21 so t = 18

The speed of light is 3.00 108 meters per second. How many kilometers per hour does the speed of light translate in scientific notation?

- Quantity A is greater
- The two quantities are equal
- Quantity B is greater
- The relationship cannot be determined

**Answer:** Quantity A is greater.

Rewrite quantity B so that it has the same base as quantity A. 49−3 can be rewritten as (72)−3, which is equivalent to 7−6. We can compare the two quantities. 7−5 is greater than 7−6.
