Answer:
It will cost Mr. Smith $68 to make his suit.
Step-by-step explanation:
Since the charge $12 per hour, and it takes 4 hours to make the suit, then we need to multiply 12 by 4.
12 × 4 = 48
Now we need to add the flat rate since that is the initial charge for service.
48 + 20 = 68
This means it will cost Mr. Smith a total of $68 for his suit.
