Answer:
Step-by-step explanation:
Let the number of miles = x
C ost = Base + 0.84x
Cost = 220.71 dollars
Base = 19.95
220.71 = 19.95 + 0.84x Subtract 19.95 from both sides
220,71 - 19.95 = 0.84 x Combine
200.76 = 0.84x Divide by 0,84
200.76/0.84 = x
x = 239 miles.
Remark: The trick to this question is to make sure that total Cost, the Base amount, and cost / mile are all in dollars. Don't mix and match.
