Question

at a store,3 pounds of tomatoes cost $7.47.Based o that rate,how much will 6 pounds of tomatoes cost?

Answer 1

It would $14.94 because you have to add 7.47 since that is 3 pounds and you need so add 7.47 + 7.47 and you get $14.94

Answer 2

$14.94

Explanation:

Make a proportion

3 pounds of tomatoes cost $7.47, and 6 pounds of tomatoes cost $x

3/7.47=6/x

Cross multiply

3*x=7.47*6

3x=44.82

Divide both sides by 3

x=14.94

Another way to approach the question is, we know that 6 is 3 doubled

Since 3 doubled is 6, then 7.47 doubled will be the cost of the tomatoes

7.47*2=14.94

So, 6 pounds of tomatoes cost $14.94
