567 vacuums were sold this year the previous year 540 vacuums were sold what is the percent of increase in sales from last year to this year?

1.20%
2.5%
3.50%
4.150%
Is it 105% percent can you help?

• Math -

1.20%, 2.5%, 3.50%, and 4.150%. What you must have intended for the answers are:
20%, 5%, 50%, and 150%.
Take the difference between the vacuums sold last year and this year, divide by the number of vacuums sold last year, and change to percent by multiplying by 100. I think 5.0% is what you will obtain.
