Answer 1

Answer:

200 miles

Step-by-step explanation:

First, we plug the new information into the equation

Cost = 0.5*distance + 30

130 = 0.5*m + 30

Subtract 30 from both sides to get .5m by itself

100 = 0.5*m

Divided by 0.5, or multiply by 2, to get m by itself

200 = m

Since m = distance, 200 = distance
