John Boy and Mary Ellen own a food stand to make funnel cakes. They drive it to county fairs all over the state during the summer months. In their budget they have determined that they will have $1200 in fixed costs for the year. Each Funnel Cake that they sell uses dough, oil, and sugar which cost a total of $75 per 100 funnel cakes made, so the total cost can be calculated using the formula, C = 0.75x + 1200. For past three summers, they were able to sell their funnel cakes for $3.50 each, so the revenue can be calculated using the formula, R = 3.50x. What is the algebraic inequality needed to indicate that the cost is less than the revenue?
