Answer: Gayle gave $ 131.58 to Marcie
Tom walked 87.96 miles
Step-by-step explanation:
1) Since, Marcie walked 26.42 miles on the 1st day, 32.37 on the next day, and 28.93 on the third day.
Thus, the total miles he walk = 26.42 + 32.37+28.93 = 87.72 miles
The cost of one mile = $ 1.50
Therefore, the cost of 87.72 miles = 87.72 × 1.50 = $ 131.58
2) Also, Tom walked 0.8 as far as Marcie on the first day, 0.7 as far on them second day and 0.9 as far on the third day.
Thus, the distance tom cover, on first day = 26.50
On second day = 32.44
On third day = 29.02
⇒ The total distance he covered = 26.50 + 32.44 + 29.20 = 87.96 miles
