Answer 1

P = 25 + (15)n

Total amount paid by David = $100

Explanation:

Given:

Fixed cost of renting chain saw = $25

Variable cost of renting chain saw = $15 per hour

Time taken = 5 hour

Find;

Total amount paid by David

Computation:

Assume;

Total amount paid by David = P

Time taken = n

So,

P = 25 + (15)n

P = 25 + (15)(5)

P = 25 + 75

P = 100

Total amount paid by David = $100
