Question 674379: Harold had a summer lemonade stand where he sold small cups of lemonade for $1.25 and large
cups for $2.50. If Harold sold a total of 155 cups of lemonade and collected a total of $265, how
many cups of each type did he sell?
Answer by ReadingBoosters(3246) (Show Source): You can put this solution on YOUR website!
x = small at 1.25
y = large at 2.50
...
x+y = 155
1.25x + 2.5y = 265
...
1.25(155-y) + 2.5y = 265
193.75 - 1.25y + 2.5y = 265
1.25y = 265 - 193.75
1.25y = 71.25
large cups
...
x = 155 - 57 = small cups
