Question

A company charges it’s customer’s a monthly fee of c dollars for using x therms of natural gas using the formula c=15+0.88867x

Answer 1

Explanation:

To find the value of C for each x-value, we can simply substitute each value into the formula:

For x=50, C = 15 + 0.88867(50) = 56.4435 ≈ 56.44

For x=100, C = 15 + 0.88867(100) = 103.877 ≈ 103.88

For x=150, C = 15 + 0.88867(150) = 151.3105 ≈ 151.31

So the ordered pairs (x,C) that satisfy the equation are:

(50, 56.44)

(100, 103.88)

(150, 151.31)
