Melanie’s bedroom walls are 45% painted. The area of her walls totals 420 square feet.
What is the number of square feet of Melanie’s walls that still need to be painted?

231 sq. ft.

Step-by-step explanation:

Total of anything is 100%

45% are painted, so not painted:

100 - 45 = 55%

The number of sq. ft. that still needs to be painted is basically 55% of 420 (total sq. ft.).

55% in decimal is 55/100 = 0.55

Now we multiply this with total:

0.55 * 420 = 231 sq. ft. (remaining)
