To find out how much money Renata made delivering newspapers this year, you should follow these steps:

  1. Convert 250% to a decimal to get 2.50. (Correct)

    • 250% as a decimal is 250/100 = 2.50.
  2. Multiply 2.50 by 540 to get $1,350. (Correct)

    • This step is needed to calculate how much she made this year: \( 2.50 \times 540 = 1350\).
  3. Check your answer by using 100% + 100% + 50% to get 540 + 540 + 270. (Correct)

    • This is a way to verify the calculation. 100% of last year's earnings is $540, adding another 100% gives another $540, and 50% of $540 is $270, so \( 540 + 540 + 270 = 1350\).

The other options:

  • Convert 250% to a decimal to get 0.25. (Incorrect)

    • This is wrong; 250% is 2.50, not 0.25.
  • Multiply 0.25 by 540 to get $135. (Incorrect)

    • This is also wrong; multiplying by 0.25 would give a value significantly lower than what is required because it represents only 25%.

So, the correct steps to take are:

  • Convert 250% to a decimal to get 2.50.
  • Multiply 2.50 by 540 to get $1,350.
  • Check your answer by using 100% + 100% + 50% to get 540 + 540 + 270.
