Last year, a bakery sold W loaves of bread. This year, the bakery sold three more than twice the number of loaves of bread sold last year. If next year the bakery plans on selling twice the number of loaves of bread sold this year, how many loaves of bread does the bakery expect to sell next year?

• 2w

• 2w+3

• 4w+3

• 4w+6

Answer explanation

Last year, a bakery sold W loaves of bread. This year, the bakery sold three more than twice the number of loaves of bread sold last year, which is 2w+3. Next year, the bakery plans on selling twice the number of loaves of bread sold this year, which is 2(2w+3) = 4w+6 loaves of bread.

If 7p - 4 = 8, what is the value of p?

Answer explanation

If 7p - 4 = 8, then 7p = 12, so

p = 12/7.

Running at an average rate of 6 miles per hour, how many minutes would it take Todd to run 3 miles?

• 18

• 30

• 40

• 45

Answer explanation

There are 60 minutes in one hour, so a rate of 6 miles in one hour is equivalent to a rate of 6/60 = 1/10mile in one minute. Therefore, at this rate, Todd runs one mile in 10 minutes. It follows that it would take Todd 3 x 10 = 30 minutes to run 3 miles.

Answer explanation

Substitute the values of r = 2b and h = 5b+3 into the formula.

Richard bought 3 slices of cheese pizza and 2 sodas for $8.75. Jordan bought 2 slices of cheese pizza and 4 sodas for $8.50. How much would an order of 1 slice of cheese pizza and 3 sodas cost?

• $3.25

• $5.25

• $7.75

• $17.25

Answer explanation

Solving the equations for cheese pizza and soda, 1 slice of cheese pizza costs $2.25 and 1 can of soda costs $1.00, therefore $2.25 + 3($1.00) = $5.25.

If 5c - 2 = 3c, then 24c = ?

• 6

• 8

• 16

• 24

Answer explanation

If 5c-2 = 3c, then 2c = 2, so

c = 1. Therefore, 24c = 24(1) = 24

In the xy-plane, the slope of the line y=mx-4 is less than the slope of the line y=x-4. Which of the following must be true about m?

• m = -1

• m = 1

• m < 1

• m > 1

Answer explanation

The slope of line y = x-4 is 1 and since the slope of y = mx-4 is less y = x-4, then m must be < 1.

A history class is made up of 12 tenth graders and 9 eleventh graders. The tenth graders averaged 77 on the midterm exam, and the eleventh graders averaged 91 on the midterm exam. What was the average grade on the midterm exam for the entire class?

• 82

• 83

• 84

• 85

Answer explanation

The 12 tenth graders averaged 77, so the sum of their scores was 12 x 77 = 924. The 9 eleventh graders average was 91, so the sum of their scores was 9 x 91 = 819. For the class average:

924+819 = 1743 divided by 21 (12+9) = 83.
