Mr. Cheung set up an account in an investment company at the beginning of this year. He makes an investment on the first day of each month. He invested $4000 in the first month and increased the monthly investment by 5% in each subsequent month. (a) How much will he invest in the last month of this year?

(b) Find the total amount that he will invest in this year.

(c) If the monthly return on his investment is 3%, find the total amount that he will get at the end of the year.

The photo attached states the answer, I require the steps to it, thank you.

Factor the polynomial. b^2 + 4b + 4

Sum of the interior angles of a pentagon

Arrange the steps to solve this system of linear equations in the correct sequence. x + y = -2 2x – 3y = -9 tiles subtract 3x + 3y = -6 (obtained in step 1) from 2x – 3y = -9 (given) to solve for x. substitute the value of x in the first equation (x + y = -2) to get y = 1. the solution for the system of equations is (-3, 1). x = -15 the solution for the system of equations is (-15, 13). add 3x + 3y = -6 (obtained in step 1) to 2x – 3y = -9 (given), and solve for x. x = -3 substitute the value of x in the first equation (x + y = -2) to get y = 13. multiply the first equation by 3: 3(x + y) = 3(-2) 3x + 3y = -6.
