Question

A store has oranges on sale at $3.00 for 2 pounds.

a. How many pounds of oranges can you buy for $9?

b. Suppose each of the oranges weighs about 5 ounces. Can you buy 24 oranges for $9? Explain.

Answer 1

A / you can buy 6 pounds for 9 dollars.

B / No you cannot. If 1 orange is 5 ounces, 24 oranges all together is 7.5 pounds. Since its 2 pounds for 3 dollars, you could get 6 pounds out of the 7.5 and that would be 9 dollars. But you would have 1.5 pounds left.

Answer 2

Hello!

a) 6 pounds

$9 is three times the cost we are given. Therefore, we multiply our original two pounds by three, giving us 6.

b) You would not be able to

There are 16 ounces in a pound. If each one weighs 5 ounces, it would be 5/16 of a pound. This would be 5/16 of $1.5, which is about 0.47. If we multiply this by 24 oranges, we get a cost 11.28, which is more than $9.

I hope this helps!
