Please help with all of these 5 points per question
liberstina [14]

Answer:

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

2. C = $150

3. 800 = m

Step-by-step 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
