Grace needs to buy a new printer. The printer she wants has a price tag of $60. She has a 25% off coupon and $50 in her bank acc
aleksklad [387]

Answer:

Yes, she will have $1.96 left

Step-by-step explanation:

Initial cost : $60

Discount : 25%=0.25

Calculating cost after discount : 60-15 = 45

Calculating final cost : 45+ 3.04 = $48.04

Can she buy the printer : 50 - 48.04= $1.96

Answer : yes
