If the total number of T-shirts and sweatshirts is 58. Then the number of T-shirts is 42 and the number of sweatshirts is 16.

What is the linear system?

A Linear system is a system in which the degree of the variable in the equation is one. It may contain one, two, or more than two variables.

A vendor sold a total of 58 T-shirts and sweatshirts.

Each T-shirt cost $25, and each sweatshirt cost $40. the vendor earned $1,690 in sales.

Let x be the number of the T-shirt and y be the number of the sweatshirt.

Then the equations will be

        x + y = 58          ...1

25x + 40y = 1690      ...2

By solving the equations 1 and 2, we have

x = 42 and y = 16
