A salesperson receives a fixed monthly income of R$1,000.00 plus an additional 3% of the sales he makes during the month. What was this salesperson's income in the month that he sold R$8,000.00?

A) R$1.240,00

B) R$1.040,00

C) R$1.200,00

D) R$1.245,00

E) R$1.420,00

Resolution:

Data:

fixed income: 1,000.00

floating income: 3% on sales

current month's sales: 8,000.00

Total received in the month: fixed + floating = 1000.00 + 8000*0.03 = 1000.00 + 240 = 1,240.00

My parents said is important to make calculation in job write it to be understood for the superior, so you have to note the dates and make a calculation completely discriminate, and well named, you have to know give the name proper for each data, you can't let out or include things that aren't about the calculo, this was to be so important that would be a official redation, type why they don't ask that in concurses know do official calculation, to you give that and this be included in the documents of the files of the firm.
