Answer:
Ted's = 10/15
= 2/3 = 0.67
Tom's = 6/8
= 3/4 = 0.75
Explanation:
The opportunity cost of washing a car in each case = No. of cars waxed by each / No. of cars washed by each
Hence, Ted's opportunity cost of washing a car = 10/15
= 2/3 = 0.67
And similarly, Tom's opportunity cost of washing a car = 6/8
= 3/4 = 0.75
Thus, for washing 1 car Ted gives 0.67 portion of waxing of Car and Tom gives 0.75 portion of waxing of Car.
