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 
So total number of car washed = 80 + 12 = 92 cars per day
So option (a) is correct answer
17,000 * 17,000 * 0.15 = 43,350,000
(Hope this helps...)
If for every $10 increase sales drop by 3 units when you increase to $300 you will lose 30 units.
($10)(10) = 100
(10)(3) = 30
60 units - 30 units = 30 units.
($300)(30) = $9,000 is your weekly revenue at a price of $300 per unit.
