Mr. Ross is painting a wall that has an area of 142.5 square feet. He uses 3/4 gallon of paint to paint 1/5 of the wall. How many gallons of paint will he need to paint the entire wall?

I don't care what the area of the whole wall is, because we don't need it to solve this problem.  It's just there to confuse us.

==>  If he used 3/4 of a gallon to paint 1/5 of the wall, then in order to paint the whole wall, he'll have to use 3/4 of a gallon FIVE TIMES.

(5) x (3/4 gallon) = (15/4 gallon)  = 3-3/4 gallons

Solving this problem may be painful, but it's not difficult.

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.

i did it myself and i got 4.2 (b) hope its right
