Mr. Santos, working as a salesman for a firm, gets a salary of 5000 per month plus a commission of 10% on all sales above 2000000 per month and his total gross pay last month was 21000, how much was his total sale last month?
2160000
It is obvious that gross salary exceeding 5000 was commission. Hence we have to determine the amount whose 10% is 16000. This amount would be 160000.
His total sales would this be 2000000+160000= 2160000

Let the total sales last month be x.
Mr. Santos gets a commission of 10% on all sales above 2000000.
So, the commission earned on (x - 2000000) sales = 10% of (x - 2000000).
Mr. Santos' total gross pay last month was $21000.
Therefore,
5000 + 0.10(x - 2000000) = 21000
5000 + 0.10x - 200000 = 21000
0.10x - 200000 = 21000 - 5000
0.10x - 200000 = 16000
0.10x = 16000 + 200000
0.10x = 216000
x = 216000 / 0.10
x = 2160000
So, Mr. Santos' total sales last month were $2160000.
