she small sold cups of lemonade for $1.25 and Large cups for $2.15 Ashley sold a total of 155 cups of lemonade for $265 how many cups of each type did she sell

The answer to your question is she bought 79 large cups and 76 small cups.

Step-by-step explanation:

Data

small cups = s = $1.25

large cups = l = $2.15

total number of cups = 155

total money = $265

Process

1. - Write 2 equations to solve the problem

s + l = 155

1.25s + 2.15l = 265

2. - Solve by substitution

s = 155 - l

1.25 (155 - l) + 2.15l = 265

193.75 - 1.25l + 2.15l = 265

-1.25l + 2.15l = 265 - 193.75

0.9l = 71.25

l = 71.25/0.9

l = 79

s = 155 - 79

s = 76
