1. You and your friend are shopping for painting supplies. Your friend wants five bottles of paint and one set of paint brushes. You want seven bottles of paint and two sets of paint brushes. Each bottle of paint costs $3.69. If you and your friend’s total cost is $51.69, what is the cost of one set of paint brushes?

Answer 1

First, add to find out how many bottles of paint in all : 5 + 7 = 12
Second, multiply the number of bottles by the price : $3.69 x 12 = $44.28 Third, subtract the cost of the paint from the total cost :
$51.69 - $44.28 = $7.41
Fourth, add to find hot how many sets of paintbrushes : 1 + 2 = 3
Divide the 3 by $7.41 = $2.47
One set of paintbrushes is $2.47
