Question

Parker earned $32 by selling 27 glasses of fresh-squeezed lemonade at his lemonade stand on a Saturday morning. He charged $1.00 for a small glass and $1.50 for a large glass. Use a model to determine how many large glasses he sold.

Answer 1

Let large glass be x, small glass be y
then
x + y = 27
1.5x + y = 32
solve for x and y

Answer 2

0.5x = 5
x = 5/0.5
x = 10
y = 17

Answer 3
