For a school fund-raiser, students sold T-shirts with the school logo for $14. PLEASE HELP! They sold sweatshirts with the school logo for $20.
They sold 233 pieces of clothing and raised $3,748.
How many of each type of shirt did they sell at the fund-raiser?
Let x = the number of T-shirts sold.
Let y = the number of sweatshirts sold.

The answer is C) x+y = 233, 14x + 20y = 3748

Step-by-step explanation:

x(number of t-shirts sold) + y(number of sweatshirts sold) = 233 (total number of pieces of clothing sold)

14x (14 is the cost of each t-shirt and since x = number of t-shirts sold then it is 14x or 14 multiplied by number of t-shirts sold) + 20y (20 is the cost of each sweatshirt and since y = number of sweatshirts sold then it is 20y or 20 multiplied by number of sweatshirts sold) = 3748 (total of money raised)
