Explanation:
Let x be the number of leather jackets and y be the number of nylon jackets.
The total cost of leather jackets is $100x and the total cost of nylon jackets is $88y.
The problem states that the inventory of men's jackets is at least $4400, so we have:
100x + 88y ≥ 4400
This is the system of inequalities:
100x + 88y ≥ 4400
x ≥ 0 (since we cannot have a negative number of jackets)
y ≥ 0 (since we cannot have a negative number of jackets)
