Question

a hot air balloon is at an altitude of 240 feet. the balloon descends at 30 feet per minute. what equation gives the altitude y, in feet, of the hot air balloon after x minutes

Answer 1

To solve this problem you must follow the steps below:

1. The problem says that:

 - The hot air balloon is at an altitude of 240 feet.
 - It descends at 30 feet per minute.

 2. Therefore, you have:

 x: the time in minutes.
 y: the altitute in feet.

 3. Keeping all this information on mind, you can write the following equation:

 y=240-30x

 4. Therefore, as you can see, the answer is:

 y=240-30x
