Answer:
10x + 15y ≥ 500
x + y ≤ 50
[tex]y\geq \frac{x}{2}[/tex]
Step-by-step explanation:
Let, the number of t-shirts = x and number of sweatshirts = y.
It is given that, at most 50 items are to be sold.
Thus, x + y ≤ 50.
Also, the number of sweatshirts to be sold is at least half the number of t-shirts.
Thus, [tex]y\geq \frac{x}{2}[/tex]
Further, it is given that the profit on t-shirts is $10 and on sweatshirts is $15 with the minimum total profit is $500.
So, we get 10x + 15y ≥ 500.
Hence, the system of inequality is given as:
10x + 15y ≥ 500
x + y ≤ 50
[tex]y\geq \frac{x}{2}[/tex]
