Answer:
112
Step-by-step explanation:
If she takes 1/8 of an hour to complete one then she can finish 8 in 1 hour.
8 x 14 = 112
Let’s say Y = total amount of snow, and X = number of hours
Y = 4x + 18
83 + 96 + 88 = 267
267 / 3 = 89
(89 + x) / 2 = 90
Multiply both sides by 2.
89 + x = 180
Subtract 180 - 89.
x = 91
