Answer:

Number of car washed is 92

So option (a) is correct answer

Explanation:

It is given that 4 workers can wash 80 cars per day

Means initially 80 cars are washed per day

And it is given that rate of car wash is $5 per car

Now price of workers is $60 per day

As per car wash is $5

So number of extra car washed [tex]=\frac{60}{5}=12[/tex]

So total number of car washed = 80 + 12 = 92 cars per day

So option (a) is correct answer
