NEED HELP! if t is the number of years from now,then 1.3t+11.1 can be used to find the height of a tree t years from now. Find the height of the tree in 28 years

t is the number of years, so you're looking for the value where t= 28. so plug in 28 for t like this: 1.3(t)+11.1 and then just solve.

so i would get 47.5
