Question

A candy store is making candy packages for amusement parks. Each package contains 7 boxes. Each box contains a 5 pound bag of chocolate and 2 bags of cotton candy sugar. The bags of cotton candy sugar are all identical. All the boxes combined weighs a total of 91 pounds. How much does each bag of cotton candy sugar weigh?

Answer 1

4 pounds

Explanation:

Per package there are 7 boxes, we know that in each box there are 5 pound bags of chocolate and 2 bags of cotton candy sugar, therefore, per package is:

7 * 5 = 35 pound bag of chocolate

7 * 2 = 14 bags of cotton candy sugar

We know that all this weighs 91 pounds:

35 + 14 * x = 91

if we solve for x:

x = (91 -35) / 14

x = 4

Which means that each bags of cotton candy sugar weighs 4 pounds
