Which equation could be used to represent the scenario? The cost of Sam's car repair is $20 an hour plus $180 for parts. If the total cost was $260, how many hours did the repair take?

4 hours

Step-by-step explanation:

Let the number of hours that the repair take be represented by h.

Since the cost of Sam's car repair is $20 an hour plus $180 for parts and the total cost was $260, this can be formed into an equation as:

180 + 20h = 260.

20h = 260 - 180.

20h = 80

h = 80 / 20

h = 4

The repair took 4 hours
