The number of hats sold = x
The number of t-shirts sold = y
Cost of selling of each hat = $5 and
Cost of selling of each t-shirt = $12.
Cost of x hats at the rate $5 each = 5x and
Cost of y t-shirts at the rate $12 each = 12y.
Total cost of x hats and y t-shirts = 5x+12y.
Total amount was spent = $240.
Therefore, cost of x hats and y t-shirts should be greater than or equal to 240.
