Question

The cost of a private room at a restaurant is $400. There is also a charge for each person who attends. The total cost for a party is $775. What is an algebraic equation to represent the situation?

Answer 1

400+yp=775

775 is the total so it goes after the equal sign, 400 is what we know is spent so it goes at the beginning of the equation. We don’t know how many people attended or how much each person cost, so we have to put y for the cost of each person and p for the amount of people attending. Hope this helped
