Answer:

2\ pints

Step-by-step explanation:

step 1

Find the area of the wall

The area of the rectangular wall is

A=(8)(10)=80\ ft^{2}

step 2

Using proportion find out how many pints Kim needs to paint the wall

so

\frac{1}{42}\frac{pint}{ft^2}=\frac{x}{80}\frac{pints}{ft^2}\\\\x=80/42\\\\x=1.9\ pints

Round to the nearest whole number

1.9=2\ pints
