Answer 1

1. C = $100 = .25(m)

2. C = $150

3. 800 = m

Explanation:

1. C = $100 (flat fee rate) + .25m

2. c = $100 + .25(200 miles)

↓

c = $100 + 50

↓

c = 150

3. 300 = 100 + .25(m)

-100 -100 (subtract on both sides)

--------------------------------

200 = .25(m)

------------------- (divide by .25 to get m by itself)

.25

Therefore being 800 = m
