Question

The price of strawberries varies directly with the weight of the strawberries purchased. Two pounds of strawberries cost $6.

What is the cost of 7 pounds of strawberries?

Answer 1

$21

Explanation:

2Lbs. = $6

(2/2) = (6/2)

1Lbs. = $3

(1*7) = (3*7)

7Lbs = $21

Since strawberries are priced on weight, you first need to find the weight of one pound. The prices need to be proportional, so whatever you do to one side of the equal sign, you need to do to the other. Divide both numbers by 2. One pound costs three dollars. Then multiply both numbers by 7. Seven pounds of strawberries cost twenty-one dollars
