Concept explainers
Produce Sales A farmer’s three children, Amy, Beth, and Chad, run three roadside produce stands during the summer months. One weekend they all sell watermelons, yellow squash, and tomatoes. The matrices A and B tabulate the number of pounds of each product sold by each sibling on Saturday and Sunday.
The matrix C gives the price per pound (in dollars) for each type of produce that they sell.
Perform each of the following matrix operations, and interpret the entries in each result.
- (a) AC
- (b) BC
- (c) A + B
- (d) (A + B)C
