Gary’s lemonade stand sold small cups of lemonade for $1.25 each and large cups of lemonade for $2.50 each. If 155 cups of lemonade were sold, and Gary collected $265, how many small cups of lemonade were sold?

small cups: 98   Large cups: 57

Step-by-step 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

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
