Myra owns a car service that charges a $5 flat rate and an additional $0.50 per mile, which is represented by the equation y = 0

Mademuasel [1]

The total cost for a car with 30 miles is $20.00.

First, do 0.5 × 30 because you need to find out how much it will cost. This will give you 15. From there, add the flat rate. 15 + 5 = 20, so it will cost $20.00.
