Difficulty:Easy

A

$1.90 p + 2 = 9.60$

B

$1.90 p - 2 = 9.60$

C

$1.90 + 2 p = 9.60$

D

$1.90 - 2 p = 9.60$

College Board · Accepted Answer

The correct answer is A. Choice A is correct. It's given that p represents the number of pounds of strawberries Lorenzo purchased and Lorenzo paid $ 1.90 per pound for the strawberries. It follows that the total amount, in dollars, Lorenzo paid for strawberries can be represented by 1.90 p . It's given that Lorenzo paid $ 2 for the box of cereal. If Lorenzo paid a total of $ 9.60 for the box of cereal and strawberries, it follows that the equation 1.90 p + 2 = 9.60 can be used to find p .
