Answer 1

512 = 16
x = 1

16x = 512
x = 512 ÷ 16
x = 32

Answer: 32 miles per gallon (B)

50 = 117.50
1 = x

50x = 117.50
x = 117.50 ÷ 50
x = 2.35

Answer: $2.35 per pound (C)

Answer 2

To find the miles per gallon, you've got to divide the larger number (512) by 16, and this gives you 32. Therefore, the car is 32 miles to e gallon. You've also got to do this for the second one, and in this case, you've got to divide $117.50 by 50, and this gives you 2.35, which means that a pound of dog food costs $2.35 Hope this helps :)
