No because the last one is not correct and if you want to text me back if you won't me to do it for you for the first three you can
Answer:y=2x-1 is the right answer.
So this is how you will arrive to the answer:
The following formula models the value of a retirement account,
S = (A [ ( 1 + r ) ^ (t + 1) - 1] / r)
wherein:
A = number of dollars added to the retirement account (each year)
r = annual interest rate
s = value of the retirement account after t years
The question is:
If the interest rate is 11% then how much will the account be worth after 15 years if $2200 is added each year?
Round to the nearest whole number.
Solution:
The said formula contains the term t + 1 instead of the usual "t". Means that the formula applies only in the situation where the money is invested at the beginning of the year instead of the usual practice at the end
Given:
A = 2200
r = 0.11
t = 15
The accumulated amount:
F = A ((1 + r) ^ (t+1) - 1 / r
Substitute:
F = 2200 (1.11 ^ (15 + 1 ) - 1) /0.11
F = 86217.88664
If money is invested at the end of the year, then F = 80476.49, the difference being the investment of an extra 2200 over 15 years.
50 yards. You are going to be taking away from that 50, so "50 -" should be part of the expression. This eliminates C.
12 skirts that take 3 yards each means 3 yards * 12 skirts which is 3 * 12. This is being subtracted from 50.
We also want to subtract 9 hats * 1 yard which is 9 * 1 = 9
Our expression will look like this: 50 - 12 * 3 - 9 * 1
or 50 - 12 * 3 - 9, which is D
