The expression 2.85+2.70M gives the taxi fare in dollars for a trip of M miles. On Thursday you got a find Miss Hearst took a ta
horrorfan [7]

<u><em>Answer:</em></u>

Total fair of the two trips was $32.7

<u><em>Explanation:</em></u>

<u>We are given that the expression that taxi fair is:</u>

2.85 + 2.7M where M represents the number of miles

<u>1- For Thursday:</u>

Number of miles covered = M = 6 miles

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

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

<u>2- For Friday:</u>

Number of miles covered = M = 4 miles

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

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

<u>3- The total fair:</u>

Total fair = fair on Thursday + fair on Friday

Total fair = 19.05 + 13.65 = $32.7

Hope this helps :)
