Lee needs to mix 3.5 gallons of liquid fruit punch concentrate with 3gallons of water to make fruit punch. He wants to make 32.5 gallons of fruit punch. How much fruit punch concentrate will he need?
3.5 / 3 = 6.5 (3.5 + 3)
32.5 ÷ 6.5 = 5, which means he needs to make 5 batches.
3.5 gallons of fruit punch concentrate per batch, which means he'll need 3.5 * 5 = 17.5 gallons of fruit punch concentrate :)
