To do it you have to find 35% of 1500 by multipling 1500 by 0.35 to get 526. Then subtract that fron 1500 and contine on but with the answer fron the previous one your answer so like this:
1500 x 0.35 = 526
1500 - 526 = 974
974 x 0.35 = 340.9
974 - 340.9 = 633.1
633.1 x 0.35 = 221.59
633.1 - 221.59 = 411.51
411.51 x 0.35 = 144.03
411.51 - 144.03 = 267.48
SO THE ANSWER WOULD BE 267.48.
Hope you understand....
