Question 7 • Common Core Math 7 B-IC

Maribel was working at the fruit stand and had to find how much change to give a customer. The customer bought 11 oranges at $0.65 each and paid with a $10 bill. Use c to represent the amount of change and choose the correct equation. 11(0.65) + c = 1011(0.65) = 10 + c-10 + c = 11(0.65)10(0.65) + c = 11

Answer
A
11(0.65) + c = 10
B
11(0.65) = 10 + c
C
-10 + c = 11(0.65)
D
10(0.65) + c = 11

Explanation

The cost of 11 oranges is 11 × $0.65, or $7.15. The customer pays $10, which covers the oranges plus the change c, so the equation is 11(0.65) + c = 10. This is choice A.
