Answer: He will need
3\frac34 gallons of paint to paint the entire wall.

Explanation:

Given : Area to paint = 142.5 square feet

Paint used to paint
\frac15 of the wall =
\frac34 gallon

Paint used to paint complete 1 wall =
5*\frac34 gallons

Paint used to paint complete 1 wall
=(15)/(4)=3(3)/(4) gallons

Hence, he will need
3\frac34 gallons of paint to paint the entire wall.
