Write a system of equations to represent each scenario, then solve to answer the question. 1. Teresa is organizing a community dinner to raise money for student activities. It costs $100 to rent the dinner hall
and $3 to make each dinner. She's charging $8 per dinner. This is all a risk though, because she can lose money
if not enough people come. How many dinners does she need to sell to break even?
Write a system of equations model her costs and revenues based on how many dinners she sells.
