Last year, the NKU bookstore sold 100 long sleeve t-shirts, 200
short sleeve t-shirts, and 50 tank tops at the on-campus location.
In addition,60long sleeve t-shirts, 150short sleeve t-shirts, and
20 tank tops were purchased online from theNKU bookstore. Long
sleeve t-shirts sell for $50 each, short sleeve t-shirts sell for
$30 each, and tank tops sell for $20 each. Create a sales matrix
and a price matrix to show how matrix multiplication may be used to
compute the total revenue for shirts sold at the NKU bookstore last
year. Then multiply the matrices to determine the total revenue at
the on-campus store and the online store.
