Question

If you have $4.00, how many pounds of apples can you buy?

A. 7 pounds
B. 7/4 of a pound
C. 4/7 of a pound
D. 2 2/7 pounds

Answer 1

`2 (2)/(7)` pounds, D

Explanation:

1 pound of apples = 1.75 dollars.

Set the number of pounds of apples as x.

Then, we can write this equation.

1.75x = 4

`(7)/(4)`x = 4

Divide both sides by
`(7)/(4)`

x =
`(4)/(1)` *
`(4)/(7)`

x =
`(16)/(7)`

x =
`2 (2)/(7)`

Thus, the answer is D, x =
`2 (2)/(7)` pounds
