Ashley sold 98 small cups and 57 large cups of lemonade.
Step-by-step explanation:
Given,
Price of small cup of lemonade = $1.25
Price of large cup of lemonade = $2.50
Total cups sold = 155
Total worth of cups = $265
Let,
x represent the number of small cups sold
y represent the number of large cups sold
According to given statement;
x+y=155 Eqn 1
1.25x+2.50y=265 Eqn 2
Multiplying Eqn 1 by 1.25
Subtracting Eqn 3 from Eqn 2
Dividing both sides by 1.25
Putting y=57 in Eqn 1
Ashley sold 98 small cups and 57 large cups of lemonade.
