a.

Answer to Problem 7PT
The total amount paid for books by himis
Explanation of Solution
Given information:
A table that depicts the cost and selling price of different books.
20 sets of encyclopedias, 32 sets of science books and 14 sets of literature books were sold by him.
Calculation:
Consider the provided information thata table that depicts the cost and selling price of different books.
20 sets of encyclopedias, 32 sets of science books and 14 sets of literature books were sold by him.
Construct a row matrix and each column of it represent the number of each book sold.
The dimension of the matrix obtained above is
Denote the three rows of the matrix as three different books and 1 column as cost of the books.
Therefore, the he total amount paid for books by him is the multiplication of number of each book by its cost.
Thus, the total amount paid for books by him is
b.
To calculate: The total amount paid for books by buyer.
