1 answer
To find your elevation after 60 seconds of skiing, you can substitute \( x = 60 \) into the equation \( y = -30x + 6,000 \):
\[ y = -30(60) + 6,000 \]
Calculating the right side:
\[ y = -1800 + 6000 = 4200 \]
So, after 60 seconds of skiing, you will be at an elevation of 4,200 feet high.
Therefore, the correct response is: After 60 seconds of skiing, you will be 4,200 feet high.
