Mr Avery Needs to repaint the outside of his house. He estimates that the area he needs to paint is about 1600 Each gallon of pa

Tju [1.3M]

Answer:

Mr. Avery will need to buy 5.4 gallons of paint.

Step-by-step explanation:

We have been given that Mr. Avery estimates that the area he needs to paint is about 1600 and each gallon of paint will cover about 250 sq feet.

So to find the number of gallons of paint needed to paint the outside of house we will divide total area to be painted (1600 sq. ft) by area covered by gallon of paint.

$\text{The number of gallon required to paint}=\frac{\text{Area of the house to be painted}}{\text{Area painted by 1 gallon of paint}}$

Since Mr. Avery has 1 gallon of paint left over from the last time he painted that he can use this time, so Mr. Avery will need one gallon less. We can represent this information as:

$\text{The number of gallon required to paint}=\frac{\text{Area of the house to be painted}}{\text{Area painted by 1 gallon of paint}}-1$
