Answer:
A) The repair bill would be at least $320 after 8 hours
B) The repairman would have worked for 5 hours
Step-by-step explanation:
A) Set up your equation with x equaling hours
30x + 80 = 320
subtract 80 to the opposite side of the equation
30x = 240
divide by 30
30x/30 = 240/30
x = 8
B) Set up your equation with x equaling hours
30x + 80 = 230
subtract 80 to the opposite side of the equation
30x = 150
divide by 30
30x/30 = 150/30
x = 5
