Answer:
x≈231.123
Step-by-step explanation:
1) Make a ratio 314/2512= x/1584
2) Use the concept of cross multiplication and get 314*1584=2512x
3) Use Algebra:
314*1584=497,376
497,376/2152=2512x/2152
x≈231.123
Answer:
Option A : y = 40x - 85 is the correct answer.
Step-by-step explanation:
Given that:
Cost of purchasing supplies = $85
Cost charged for cleaning a pool = $40

x be the number of pools cleaned.
y be the profit
Profit = Cost of pools cleaned - purchase price of supplies
y = 40x - 85
Hence,
Option A : y = 40x - 85 is the correct answer.
