Jocelyn
bought 2 sweaters for the same price.
She paid $23.56, including sales tax of $1.36 and a $5.00 discount coupon.
Problem: Find the price of 1 sweater before the tax and coupon
=> 2 sweaters = 23.56 dollars included tax and discount
=> remove the tax and discount first
=> 23.56 + 5.00 = 28.56 dollars since this is a discount, we need to add
this to the amount
=> 28.56 – 1.36 = 27.2 dollars is the
price of 2 sweaters
=> 1 sweater costs 13.6 dollars
