Question 782451: Here is what I'm trying to figure out. An artist paints designs on t-shirts. it takes 12 minutes to set up the equipment and 36 minutes to clean the equipment and put it away. Once everything is set up, it takes about 9 minutes to paint a design on each t-shirt. How many t-shirts can the artist make in 2 hours ? why? (provide an equation as well)
Answer by josgarithmetic(39617) (Show Source): You can put this solution on YOUR website!
Let n = number of t-shirts.
2 hours is 120 minutes.

The time to do everything must be no greater than 120 minutes.
Account for all time quantities.

Once solved for n, you need to pick the nearest whole number which makes sense. The reason is that the artist must finish a t-shirt that he starts; he cannot paint only a partial picture.
