Total fair of the two trips was $32.7

Explanation:

We are given that the expression that taxi fair is:

2.85 + 2.7M where M represents the number of miles

1- For Thursday:

Number of miles covered = M = 6 miles

Substitute with M=6 in the given equation to get the fair on Thursday as follows:

Fair on Thursday = 2.85 + 2.7(6) = $19.05

2- For Friday:

Number of miles covered = M = 4 miles

Substitute with M=4 in the given equation to get the fair on Friday as follows:

Fair on Friday = 2.85 + 2.7(4) = $13.65

3- The total fair:

Total fair = fair on Thursday + fair on Friday

Total fair = 19.05 + 13.65 = $32.7
