Atheater club sold 540 tickets . on the first day, 55% of the 40 tickets were sold. how many tickets were sold on the first day ?

To find 55% of 40, you'll first need to convert 55% to a decimal. To convert a percent into a decimal, you'll need to move the decimal point to the right twice, so 55% will turn to 0.55. After, you'll need to multiply 0.55 w/ 40 which will give you 22 as your answer.

I hope this helps!
