The amount deposited in the first year is $150. The amount deposited in the second year is $150 + $45 = $195. The amount deposited in the third year is $195 + $45 = $240. Continuing in this manner, the amount deposited in the twentieth year is $150 + $45(20 - 1) = $150 + $45(19) = $150 + $855 = $1005. The total amount deposited in the twenty years is $150 + $195 + $240 + ... + $1005 = $11,550.
