7. Elizabeth is trying to determine the best way to invest in her retirement. Retirement Saving Plan #1 will start with $2000 at age 20 and earn 2.8% interest compounded annually. Retirement
Saving Plan #2 will start with $2500 at age 25 and earn 5% simple interest every year.
a) Which retirement plan will she earn the most money by age 65?
b) What is the difference in the afhount of money earned in both plans?

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.

correct answer is infinitely many solutions

step-by-step explanation:

2(2x + 3) = -4 + 2(2x + 5)

solving the above equation:

4x + 6 = -4 +4x +10

combining like terms

4x -4x = -4+10-6

0=0

since both sides are 0=0, we end up into true statement it means it has infinite many solutions.

so correct answer is infinitely many solutions
