Respuesta :
The area with 2 3/8 gallons of paint cover is 950 ft².
What is the unitary method?
The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
Given;
1 gal = 400 ft²
2 3/8 gal = ? ft²
To solve, similar ratios with units gal/ft²
(1)/(400) = (2 3/8)/(x)
Now, multiply both sides by (x) and divide both sides by (1)/(400),
x = (400)*(2 3/8)/(1)
x = 400*(2 3/8)
x = 400*2 + 400*3/8
x = 800 + 150
x = 950 ft²
Thus, The area with 2 3/8 gallons of paint cover is 950 ft²
