We are working on an optimization model in Solver, and need to add a constraint. Our organization makes two different products, product x and product y. Product x requires 3 hours of manufacturing time. Product y requires 5 hours of manufacturing time. We have a maximum of 100 hours of manufacturing time available. How would you enter the constraint?

• A. 3x - 5y <= 100
• B.3x + 5y >= 100
• C.3x + 5y <= 100
• D. 3x - 5y >= 100
