Plz help (algebra) if I dont get this, I am grounded permenantly.

i dont want you too get grounded

Step-by-step explanation:

A)

For option 1, the type of function is linear because the series of interest earned increases arithmetically in $110 per year.  

For option 2, the type of function is exponential because the series of interest earned increases geometrically in $1.09 per year.

b)

The option 1 refers to a simple interest with a function: f(n) = $1000 + $110*n.

The option 2 refers to a compound interest with a function: f(n) = $1000*(1.09^n)

c)

After 20 years, she would get:

in option 1, f(20) = $1000 + $110*20 = $3200

in option 2, f(20) = $1000*(1.09^20) = $5604.41

There is a significant difference between these options because the interest earned ACCRUES on the principal amount and the accumulated interest of previous periods.
