Answer:
The number of cans of primer purchased was 4
Step-by-step explanation:
Let
x ----> the number of cans of premium paint purchased
y ---> the number of cans of primer purchased
we know that
A painter purchased a total of 16 cans of premium paint and primer
so
[tex]x+y=16[/tex] -----> equation A
The painter spent a total of $475.84
so
[tex]32.99x+19.99y=475.84[/tex] ----> equation B
Solve the system of equations by graphing
The solution is the intersection point both graphs
The solution is the point (12,4)
see the attached figure
therefore
The number of cans of primer purchased was 4
