Can you please check my work. I asked this question yesterday but no one helped me. Thank you , I really appreciate it

Question

A hot air balloon was at a height of 60 feet above the ground when it began to ascend. The balloon climbed at a rate of 15 feet per minute.
a) make a table that shows the height of the air balloon after climbing for 1,2,3,&4 minutes.
minutes:1 2 3 4
-------------------
height:15 30 45 60
(ft)climbed

b)let T represent the time in minutes since the balloon began climbing. wRITE AN ALGEBRAIC EQUATION FOR THE sequence that can be used to find height,h,of the balloon after T minutes.

h=15T
c) use your equation from part b to find the height, in feet, of the hot air balloon after climbing for 8 minutes.
h=15T
h=15(8)
h=120 ft
Are these correct. Thanks for taking the time to check my work

Answer 1

Since it asked for the height of the balloon , should you not have added the original 60 feet to each of your answers ?
e.g. after 2 seconds
= 60 feet + 30 new feet = 90 ft

so I would give my equation as
height = 60 + 15t

Your answers describe the height of the balloon after it started to rise.
