Unit 3 Test Form A

Maria is bringing her sick dog Pedro in for a series of appointments at the veterinary clinic. Her total cost over the course of treatment will be $150 for tests and medicine plus $30 per appointment, a. Part A: What is the equation to show the total cost, t, she will owe?

• t = 150 - 30a

• t = 150a + 30

• t = 30 + 150a

• t = 30a + 150

Part B: The clinic offers Maria a 15% discount off of her total cost. Write an equation to show her updated cost. Select all that apply.

• (30a + 150) - 0.15 * (30a + 150)

• (30a + 150) + 0.15 * (30a + 150)

• (30a + 150) * 0.85

• (30a + 150) / 0.85

Part C: Using one of the equations you chose on Part B, solve for Maria’s total discounted cost if Pedro’s treatment requires three veterinary appointments.

• $150

• $200

• $250

• $300

• A

• B

• C

• D

Factor the GCF to write an expression that is equivalent to 8 + 24x.

• 8(1 + 3x)

• 4(2 + 6x)

• 8(1 + 2x)

• 4(2 + 12x)

Which of the following are equivalent to 3p(p + 2)? Choose all that apply.

• 6p + 3p²

• 3(p² + 2p)

• (p + 2)3p

• 3p + 6

• p · 3(p + 2)

Kayla's garden has a width of 4 ft. and a length of 8x+2 ft. Part A: Choose two equivalent expressions to describe the perimeter of Kayla’s garden.

• 4 + 8x + 2

• 4 + 4 + (8x +2) + (8x+2)

• 4(8x + 2)

• 2(4) + 2(8x + 2)

Part B: How can you check to see if your two expressions from Part A are equivalent?

• By simplifying both expressions and comparing the results.

• By checking if both expressions have the same number of terms.

• By substituting the same value into both expressions and comparing the outputs.

• By ensuring both expressions are in the same form.

Part C: What is the total perimeter of Kayla’s garden if x=2? The total perimeter is ______ feet.
