Answer :
Answer:
- 300 miles
Step-by-step explanation:
Let
- y- the amount of charge,
- x - the number of miles
The equations as per question are below
Crazy Curly's
- y = 0.3x + 20
Bill's Beauties
- y = 0.2x + 50
Solve the system by substitution
- 0.3x + 20 = 0.2x + 50
- 0.3x - 0.2x = 50 - 20
- 0.1x = 30
- x = 30/0.1
- x = 300
