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

No, it isn't 105% (which isn't one of your answers) and your answers are written in VERY confusing fashion. Read your posts and it appears the answers are

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.

To calculate the percent increase in sales from last year to this year, you can use the formula:

Percent Increase = (Number of Increase / Original Number) * 100

Given that 567 vacuums were sold this year and 540 vacuums were sold the previous year:

Number of Increase = 567 - 540 = 27
Original Number = 540

Percent Increase = (27 / 540) * 100

Calculating this, we get:

Percent Increase ≈ 5%

So the correct option from the given choices is 2. 5%

To calculate the percent increase in sales from last year to this year, you can follow these steps:

1. Find the difference in sales between this year and last year:
Increase in sales = Number of vacuums sold this year - Number of vacuums sold last year
= 567 - 540
= 27

2. Calculate the percent increase using the formula:
Percent increase = (Increase in sales / Number of vacuums sold last year) * 100

Plugging in the values:
Percent increase = (27 / 540) * 100
= 5%

Therefore, the percent increase in sales from last year to this year is 5%. Thus, the correct answer is option 2.
