Question

1. at the start of the day, there was 12 inches of snow on the ground. since then, 20% of the snow has melted. which expression represents the inches of snow left on the ground? a. 0.2·12 b. 0.8·12 c. (1 + 0.2)·12 d. 8 - 0.20

Explanation:

Step1: Determine remaining snow percentage

20% melted, so remaining is \(100\% - 20\% = 80\% = 0.8\).

Step2: Calculate snow left

Multiply remaining percentage (0.8) by initial snow (12), so expression is \(0.8 \cdot 12\).

Answer:

b. \(0.8 \cdot 12\)
