She had to pay a flat fee of $2.05 plus $0.90 per mile. The total coat was $5.65 how many miles was the taxi trip?

4 miles

Step-by-step explanation:

If you subtract 2.05 with 5.65 it will get 3.60. you then divide that by 0.90 and you'll get the final answer of 4 miles

OR

2.05 + 0.90m = 5.65

0.90m = 5.65 - 2.05

0.90m = 3.60

m = 3.60 / 0.90

m = 4 <== = the taxi trip was 4 miles
