Question

Ben bought 3 oranges for 89 cents each and 4 apples for x dollars each. He spent $7.15 for the apples and oranges.

Which equation could be used to find the cost of each apple?
Responses

A4x + 3(0.89) = $7.15

B3x + 4(0.89) = $7.15

C$7.15 − 3x = 0.89


D4x − 3(0.89) = $7.15
4x − 3(0.89) = $7.15

Question 2
Which sequence of arithmetic operations could be used to solve for the cost of each apple?
Responses

A Subtract 0.89 from $7.15; divide difference by 4

B Subtract 0.89 from $7.15; divide difference by 7

C Multiply 0.89 by 3; add product to $7.15; divide sum by 4

D Multiply 0.89 by 3; subtract product from $7.15; divide difference by 4

Answer 1

The correct answer for the first question is B: 3x + 4(0.89) = $7.15. This equation represents the cost of 3 oranges (3(0.89)) plus the cost of 4 apples (4x) adding up to $7.15.

For the second question, the correct answer is A: Subtract 0.89 from $7.15; divide the difference by 4. This sequence of operations will give you the cost of each apple.
