Let the profit from each chocolate fudge bar be $1.50, the profit from each ice-cream sandwich be $1.00, and the profit from each frozen fruit bar be $0.50.
To make a profit of at least $700, the total profit from selling c chocolate fudge bars, s ice-cream sandwiches, and F frozen fruit bars must be greater than or equal to $700. We can write this as an inequality:
1.5c + 1s + 0.5F >= 700
This inequality states that the total profit from selling c chocolate fudge bars, s ice-cream sandwiches, and F frozen fruit bars must be greater than or equal to $700.
