Pat is buying supplies for S'mores. He and his friends will each eat 3 S'mores. There are 8 of them in total. It costs $3 in supplies to make 4 S'mores. How much will it cost to buy all the supplies?
They are making 24 S'mores because 8 x 3 = <<8*3=24>>24
Each S'more costs $.75 to make because 3 / 4 = <<3/4=.75>>.75
It will cost $18 to make them all because 24 x .75 = <<24*.75=18>>18
