Jackson is starting a new exercise program that awards him points for maintaining progress. The system provides him a one-time allotment of 30 points for starting the program and then 2
additional points for each day he participates. Write an equation for T(d), the total, in points,
after d, number of days.

answer is  

a.

p = 78

step-by-step explanation:

8.75

how-to:

first, we need to find what we have to work with.

since i know that we have 7 (years) and 0.8 (inches), we can use these to solve and find the equation!

secondly, what you want to do, is see that we need to know how much growth out of the 0.8 inches he got in only 1 year, instead of 7 years.

let's try to divide.

7 ÷ 0.8 = 8.75
