Answer:

C) 20 hours

Step-by-step explanation:

x = number of hours

A yard cleanup service charges a $380 fee plus $14 per hour.

380 + 14x

Another cleanup service charges a $260 fee plus $20 per hour.

260 + 20x

How long is a job for which the two companies' costs are the same?

380 + 14x = 260 + 20x

380 - 260 = 20x - 14x

120 = 6x

20 = x
