The cost per square foot of laminate flooring is $1.88 and the cost per square foot of carpet is $2.49
Step-by-step explanation:
Let
x -----> the cost per square foot of laminate flooring
y ----> the cost per square foot of carpet
we know that
750x+525y=2,717.25 -----> equation A
100x+75y=374.75 ------> equation B
Solve the system by graphing
The solution of the system is the intersection point both graphs
The solution is the point (1.88,2.49)
see the attached figure
therefore
The cost per square foot of laminate flooring is $1.88 and the cost per square foot of carpet is $2.49
