he cannot afford to buy his dad the shirt
Step-by-step explanation:
Amount Jesse has = $23
Cost of shirt = $30
coupon = 20%
If coupon is applied:
discount = $30 × 20% = 30 × 0.20
discount = 6
The sales price of the shirt after applying coupon = Cost of shirt - discount
The sales price of the shirt after applying coupon = 30 - 6
The sales price of the shirt after applying coupon = $24
The amount Jesse has is less than the sales price of the shirt after applying coupon
$23 < $24
Since the amount he has is less, he cannot afford to buy his dad the shirt
