Josh is saving up for a box of cookies. To raise the money, he is going to make bracelets and sell them. It costs $1 for supplies for each bracelet and he sells each one for $1.5. If he makes 12 bracelets and after buying the cookies still has $3, how much did the box of cookies cost?He makes $.5 profit on each bracelet because 1.5 - 1 = <<1.5-1=.5>>.5
He earns $6 because 12 x .5 = <<12*.5=6>>6
The cookies cost $3 because 6 - 3 = <<6-3=3>>3
