# To paint a room, Suzanne uses blue and white paint in the ratio of blue:white = 8:3. What was the total number of gallons of paint used if she used 6 gallons of blue paint?

8x=18(multiply your means and your extremes)

x=18/8 (transpose or transfer all the variables on the left side while the constants on the other side)

x= 2 1/4 ( two and one-fourth)

so if there are 6 gallons of blue paint used already you just add the another 2 1/4 gallons of white paint. so all in all suzane used 8 1/4 galloons of paint. :)
