A After 60 seconds of skiing, you will be 7,800 feet high.

B After 60 seconds of skiing, you will be 4,200 feet high.
After 60 seconds of skiing, you will be 4,200 feet high.

C After 60 seconds of skiing, you will be 5,820 feet high.

D After 60 seconds of skiing, you will be 6,030 feet high.

Answer 1

To find the elevation level after 60 seconds of skiing, you need to substitute x = 60 into the equation y = -30x + 6000.

y = -30(60) + 6000

y = -1800 + 6000

y = 4200

Therefore, after 60 seconds of skiing, you will be 4,200 feet high.

The correct answer is B.
