Answer:
She bought 15 napkins
Step-by-step explanation:
First find the price before coupon
1.5 * n where n is the number of napkins
Then subtract the coupon
1.5n - 20
This is the price she paid before tax
1.5n -20 = 2.5
Solving for n
Add 20 to each side
1.5n -20+20 = 2.5+20
1.5 n= 22.50
Divide each side by 1.5
1.5n/1.5 = 22.5/1.5
n =15
She bought 15 napkins
