in a circle graph above you can see that 47 percent of the companys monthly income is used to pay the owners personal salary if the amount of the owners personal salary was 2,176.10 this month what was the companys total income this month

Answers

the first thing you have to do is to divide the personal income by the percen it takes up

2,176.10/47=46.3

that means that 46.3 is 1% of the whole, so if we multiply it by 100 you will get the whole

46.3*100=4630

so the answer is

4,630
