Question

a store has apples on sale for 3.00 for 2 pounds. how many pounds of apples can you buy for $9. if an apple is approximately 5 ounces how many apples can you buy for $9. explain your reasoning

Answer 1

16oz in a pound.
you can only buy 6lbs.
1lbs of apples would be 3 with one Oz remaining.
6lbs of apples would have 6oz remaining. so that'd be an extra apple.
6lbs of apples would be 18 apples.
18+1=19
19 apples

Answer 2

If two pounds of apples cost $3.00 you can buy 6 pounds for $9.
3÷2 = 1.5, so you can buy 1 lb of apples for $1.50
9 ÷ 1.5 = 6, so you can buy 6 lbs of apples for $9
There are 16 ounces in a pound, so 6 pounds is equal to 96 ounces (6*16)
96 ÷ 5 is 19.2
You cant buy 0.2 apples, so 19.2 must be rounded down to 19 apples

You can buy 19 apples for nine dollars.
