    Convert 250% to decimal to get 2.50.

    Multiply 2.50 by 540 to get $1,350

    Step-by-step explanation:

    Percentage calculations

    The percent sign % means one-hundredth of something. 15% is 15/100=0.15. We can safely divide the amount in % and divide it by 100 to get the decimal expression.

    Knowing Renata earned $540 last year and this year made 250% of that quantity, we can write 250%=250/100=2.5 times the earnings of last year.

    The first step should be

    Convert 250% to decimal to get 2.50.

    Now we must multiply 2.50 by 540 to get $1,350

    Checking, adding 100%+100%+50% of 540 is 540+540+270=$1,350 as expected
