Speedy Boat Rental charges a $15 deposit fee plus $2 for each hour of use to rent a paddle boat.  Write an equation for C, the total cost, to rent the boat for h hours.

• h = 2C + 15

• C = 15h + 2

• h = 15C + 2

• C = 2h + 15

A man is climbing down from 100 feet high descending 30 feet per minute. Which function models his descent?

• y = 100 - 30x

• y = 100 + 30x

• y = 100x + 30

• y = 100x - 30

What is the first step to solving this problem?

• Multiply 5 times x

• Add 4 to both sides

• Subtract 4 from both sides

• Divide by 5 on both sides

What is the first step to solving the following problem? 9x - 4 = 14

• Divide by 9 on both sides

• Multiply by 9 on both sides

• Subtract 4 from both sides

• Add 4 to both sides

What is the LAST operation to perform in the following problem? 12x + 3 = 27

• Divide by 12 on both sides

• Multiply by 12 on both sides

• Subtract 3 from both sides

• Add 3 to both sides

What is the first operation that should be done in the following problem? 7(m + 5) =21

Circle all of the equivalent answers to the following:

a + a + 3 + 3 + a + 3 + 3 = 24

• 4a + 12 = 24

• 3a + 12 = 24

• 3(a + 4) = 24

• 3a = 12

What two numbers would multiply to make the number on top and add to make the number on the bottom?

• 3

Here is a pattern of squares. A represents the number of small squares in the pattern as a function of x, the step number. Which expression could define A?

Edgar is constructing a rectangular play area against an exterior wall of his house for his guinea pig. He uses 60 feet of fencing material to enclose 3 sides of the play area. Write an equation to represent l, the length of the play area in feet, as a function of w, the width in feet. (Perimeter=add up all the sides)
