Answer:
Each person's share of the profit is $ 125.
Explanation:
Given : Three friends are holding a car wash and agree to split the profits equally.
Also, They purchase supplies for $ 75 and their total income is $ 450.
We have to find each person's share of the profit.
Since, total income consist of profit and cost of material used.
Profit + cost of supplies = $ 450.
Given they purchase supplies for $ 75
Profit + $ 75 = $ 450.
Profit = $ (450 - 75) = $ 375
Their total profit is $375.
Given they split the profits equally.
Thus, dividing the profit $ 375 into 3 parts , we have,
$ 125 each .
Thus, each person's share of the profit is $ 125.
