Question

Kym is renovating the first floor of her home. She bought 750 square feet of laminate flooring and 525 square feet of carpet and paid $2717.25. She went back to the store and brought an additional 100 square feet of laminate flooring and 75 square feet of carpet and paid $374.75. Find the cost per square foot of each type of flooring.

Answer 1

Answer:

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
