The best answer is Option A.
Step-by-step explanation:
Increased height of snow = 17 inches
First increase = 5% = 0.05 (Converting the percentages dividing by 100)
Second increase = 8% = 0.08
Third increase = 11% = 0.11
We will first start from where the snowfall has end, therefore,
Third increase = 11% of 17 inches
Third increase =
Subtracting from original height of snow = 17 - 1.8 = 15.2 inches
Second increase = 8% of height before third increase
Second increase =
Height before second increase = 15.2 - 1.2 = 14 inches
First increase = 5% of height before second increase
First increase =
Height before first increase = 14 - 0.7 = 13.3 inches
The snow was 13.3 inches high before it started to snow.
The best answer is Option A.
