let x = # of hours of labor done on the car

jim_thompson5910 · Answer

so if "A car repair shop charged $80 per hour for labor ", then a total of 80x dollars will be charged for labor only

add on the parts cost to get 80x + 210

jim_thompson5910 · Answer

total cost = 80x + 210

this total cost is given to be $490, so

80x + 210 = 490

solve that for x to get your answer
