Arepair company's charge for repairing a certain type of copy machine fits the model y = 47.38 + 0.617x where y is the number of dollars charged and x is the number of minutes the repair person is on the job. how many minutes would it take for the cost of repair to reach $130? (round to the nearest minute.)
a. 203
c. 134
b. 287
d. 13

c is the correct answer

Step-by-step explanation:

A repair company's charge for repairing a certain type of copy machine fits the model y = 47.38 + 0.617x

where y is the number of dollars charged and

x is the number of minutes the repair person is on the job.

Therefore, to determine the number of minutes that it would take for the cost of repair to reach $130, we would substitute y =130 into the given model. It becomes

130 = 47.38 + 0.617x

0.617x = 130 - 47.38 = 82.62

x = 82.62/0.617 = 134 minutes

answer: 0,6

step-by-step explanation:

this would make it the y intercept.
