3. A hot air balloon is at a height of 2,250 feet. It descends 150 feet each minute. Find it's height after six, eight, and ten minutes. Make a table to show the pattern of heights. Write an expression for the balloon's height at "m" minutes.

This one just has me completely lost. Do I divide or subtract or...? I have not the slightest idea what the answers are, how to set up the expression, how to make the table, etc. This is why I need help urgently, PLEASE. I'll try, though...

2,250 - 150 ÷ m

2,250 - 150 ÷ 6 =
2400 ÷ 6 = 400

2,250 - 150 ÷ 8
2400 ÷ 8 = 300

2,250 - 150 ÷ 10
2400 ÷ 10 = 240

Is this correct, or is it 2,250 ÷ 150 - m? I'm so lost. :/ Also, what's the pattern? I've been asking since last night with absolutely no response whatsoever. I apologize, as I know you are busy with many other questions.

6 * 150 = 900 feet dropped in 6 minutes
2250 - 900 = 1350 height after 6 minutes

Take it from there.
900ft after 6minutes
1200 after 8minutes
750 after 10minutes
give me the answer
Not understand because in my text book answer key the answer is 450 after 12min
