Each drink uses 1.5 cups because 1/4 cup + 1 and 1/4 cup = <<1.5=1.5>>1.5 cups

The pitcher contains 12 total drinks because 18 / 1.5 = <<18/1.5=12>>12

There are 15 cups of lemonade in the pitcher because 12 x 1 and 1/4 = 15

Abigail is trying a new recipe for a cold drink. It uses 1/4 of a cup of iced tea and 1 and 1/4 of a cup of lemonade to make one drink. If she fills a pitcher with 18 total cups of this drink, how many cups of lemonade are in the pitcher?
