the complete question in the attached figure
Part A
we know
price poster boards----------- > $0.75
let
p------------- > number of poster boards
q------------- > money spends on poster boards----------> $2.25
q=p*0.75---------> p=q/0.75=2.25/0.75=3
the answer part A is 3
Part B
Let
x-------------- >number of paint brushes------------ > $0.95
y-------------- >number of jar of paint ------------ > $0.99
we know
0.95x+0.99y=4.87
using a graph tool
see the attached figure
the solution is the line shown in the graph
the solution must be a pair of whole numbers, <span>the only pair that meets that condition is the point (2,3)x=2-------------- ></span>number of paint brushes
y=3-------------- >number of jar of paint
