Step-by-step explanation:
I used an excel spread sheet for the below numbers
1 1500 0.065
2 1597.5 0.065
3 1701.3375 0.065
4 1811.924438 0.065
5 1929.699526 0.065
6 2055.129995 0.065
7 2188.713445 0.065
8 2330.979819 0.065
9 2482.493507 0.065
10 2643.855585 0.065
11 2815.706198 0.065
12 2998.727101 0.065
13 3193.644362 0.065
14 3401.231246 0.065
15 3622.311277 0.065
16 3857.76151 0.065
17 4108.516008 0.065
18 4375.569549 0.065
19 4659.981569 0.065
20 4962.880371 0.065
21 5285.467595 0.065
at 18 he has 4,375.56 at 21 he would have 5.285.46
5,285.46 - 4,375.56 = 909.9
that's your answer for 1
