Answer 1

Answer:

Ayden met his goal of painting atleast 80% of 500 square meters of a house's walls.

Step-by-step explanation:

We are given the following in the question:

Area of house wall to be painted = 500 square meters

Ayden's goal = Atleast 80% of the wall

Area covered by Ayden = 415 square meters

Calculation:

$80\%\times 500\\\\=\dfrac{80}{100}\times 500\\\\= 400\text{ square meter}$

Thus, Ayden's goal is to atleast cover 400 square meter of wall.

Since,

$415 > 400$

Thus,  Ayden met his goal of painting atleast 80% of 500 square meters of a house's walls.
