Tina's car needs to be repaired. As auto repair shop charges Tina $42.30 for replacement parts and $22.50 per hour of labor. If Tina gets charged a total of $109.80, how many hours of labor were spent on the repair?
O 5 hours
O 4 hours
O 3 hours
O 2 hours

Just add

42.30 + 22.50 = 64.80
64.80 + 22.50 = 97.30
97.30 + 22.50 = 109.80

We added 22.50 3 time so our answer would be 3 hours

Mathematical standard

Therefore the total hours of labor spent on the repair was 3 hours.
