Step-by-step explanation:

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
