Sagot :
Answer:
3 hours
Step-by-step explanation:
3x75= 225 so you add 225 to 220 and then you get 425 so for every 3 hours he charges 75 dollars
Step-by-step explanation:
Let x = # of hours work done on the car
The inequality can written as
425 =< 75x + 200
where 425 represents the minimum cost for Hudson and 75 is the repair rate per hour charged by the mechanic. Solving this inequality, we find that
225 =< 75x
or
x >= 3
This means that the mechanic will take at least 3 hrs to work on his car.
