The complete question in the attached figure

Let 
x-----------------> number of paintbrushes----------- > $0.95 each
y---------------- > number of jar of paint-------------- > $0.99 each

the solution will be a pair of coordinates that are whole numbers -- > see the attached figure

the solution is the point (2,3)

x=2---------------------- > number of paintbrushes
