Elicia opened an account with a deposit of $2,000. The account earned annual simple interest. She did not make any additional deposits or withdrawals. At the end of 8 years, the balance of the account was $3,040. What is the annual interest rate on this account? 5.4% 5.4% 7.2% 7.2% 6.5% 6.5% 2.9%

6.5%

Step-by-step explanation:

Given : Principal amount = $ 2000

Time = 8 years

Final amount = $3040

Formula : Simple interest = Final amount - Principal amount

Simple interest = Principal x time x rate

Substitute all values in this formula , we get

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
