Answer:
Piano Play has the better deal
Step-by-step explanation:
Piano Play has the better deal because it has a lower unit rate
Make Music’s unit rate is 52.5 when you divide $525 by 10 hours
Piano Play’s unit rate is $45 when you divide $540 by 12 hours
100 divided by 2 is 50 and then divided by 6 is 8.333333 but you just round that to 8$.
