5. Ashley had a summer lemonade stand where she sold small cups of lemonade for $1.25 and large cups for $2.50. If Ashley sold a total of 155 cups of lemonade for $265, how many cups of each type did she sell?.

Answer 1

98 small cups, and 57 large cups!

Explanation:

x+y = 155

1.25x+ 2.50y = 265

1.25x + 2.50 ( 155 - x) = 265

1.25x + 387.5 - 2.50x = 265

-1.25x = 265-387.5

-1.25x = -122.5

x=98; y = 57
