A youth orchestra is selling advertising space in their music programs to raise money. The orchestra has a goal to raise $2,500 or more by selling small and large-sized advertisements to local businesses. Each small ad costs $50 and each large ad costs $125. The graph of the inequality shown below represents possible combinations of each size of advertisement that could be sold to meet or exceed the fundraising goal. In the graph, 'x' represents the number of small-sized advertisements sold and 'y' represents the number of large-sized advertisements sold. Based on the graph and the information given, write an inequality that represents how the group can determine the number of small and large ads that must be sold in order to at least reach their goal of $2,500. Type the inequality in the box below.
