Question

Dajuan is painting a mural on a rectangular

wall. The wall is 14.5 feet long and 10 feet
wide. So far, his mural covers 60% of the wall.
Dajuan will paint the remaining part of the wall
over the next four days. He will paint the same
amount of the wall, in square feet, on each of
those four days. How much of the wall, in
square feet, will Dajuan paint on each of the
next four days? Explain how you arrived at
your answer.

Answer 1

Dajuan has already painted 60% of a 145 square feet wall, which equals 87 square feet. The remaining area is 58 square feet, and he will paint an equal portion of that area over the next four days, which is 14.5 square feet per day.

Step-by-step explanation:

Dajuan is working on a mural painting on a rectangular wall which has an area of 14.5 feet by 10 feet, totaling 145 square feet. He has painted 60% of the wall so far. To find out the area covered by the mural till now, we calculate 60% of the total area: 0.60 × 145 square feet = 87 square feet. The remaining area yet to be painted is then 145 square feet - 87 square feet = 58 square feet. Over the next four days, Dajuan plans to paint the wall equally each day. Therefore, the remaining area is divided by 4 to find how much he will paint each day: 58 square feet ÷ 4 = 14.5 square feet. So, Dajuan will paint 14.5 square feet of the mural on each of the next four days.

Answer 2

Every day Dajuan will paint 14.5 square feet of the wall.

Step-by-step explanation:

Since Dajuan is painting a mural on a rectangular wall, which measures 14.5 feet long and 10 feet wide, and so far, his mural covers 60% of the wall, and Dajuan will paint the remaining part of the wall over the next four days, painting the same amount of the wall, in square feet, on each of those four days, to determine how much of the wall, in square feet, will Dajuan paint on each of the next four days, the following calculation must be performed:

((14.5 x 10) x 0.4) / 4 = X

(145 x 0.4) / 4 = X

58/4 = X

14.5 = X

Therefore, every day Dajuan will paint 14.5 square feet of the wall.
