The correct formula would be C
multiply principle ( $800) by (1+interest rate as a decimal) to the power of number of years
so you would have 800 x (1+0.03)^7
Rule needed: i^2 = -1
Standard form a + bi
(3 + 2i)(7 - 5i) FOIL
3 * 7 = 21
3 * - 5i = - 15i
2i * 7 = 14i
2i * -5i = - 10i^2 = - 10 * -1 = 10
Putting it all back together.
31 - i
