strips needed to make each style.

B. Walnut costs $1.50 per strip, maple costs $.85
per strip, and cherry costs $1.10 per strip. Write

A, B, and C and matrix multiplication to find the
total cost of Monique's wood and of Shondra's
wood. Show the matrix product you used. Th en
describe your solution method.
