Answer:
200 miles
Step-by-step explanation:
<u>Company A</u>
- Daily charge = $130
- Per mile = $0.20
- x miles per day = 130 + 0.2x
<u>Company B</u>
- Daily charge = $50
- Per mile = $0.60
- x miles per day = 50 + 0.6x
<u>Assume x miles that makes same amount for both options, then:</u>
- 130 + 0.2x = 50 + 0.6x
- 0.6x - 0.2x = 130 - 50
- 0.4x = 80
- x = 80/0.4
- x = 200 miles
