Answer: $1040
A = P + I
A = Total
P = Principal
I = Interest
First find the total amount
A = 640(4)(9)
A = 23040
Plug In the Numbers
23040 = 22000 + I
Substract 22000 on both sides
I = $1040
So, the negative would be divided out to make it 3, then square both sides to get rid of the square root and get 9, then subtract 15 and you get -6. <span />
