Alocal restaurant allows groups to rent out a party room in order to host events. the restaurant charges $600 to rent the room and an additional $10 per meal. a local school's pta wants to host an event at the restaurant and needs to determine the average cost per person attending so that they can price their tickets accordingly. each person will receive one meal. which equation can be used to determine the average cost per person, y, if x meals are served?

y = (10x + 600)/x

Step-by-step explanation:

To find the average cost, we must divide the total cost by the number of people.

The number of meals served will equal the number of people, since everybody gets just 1 meal.

Each meal is 10 dollars, plus the 600 rental fee.

The total cost will be the meal prices plus the fee, all divided by the number of people/number of meals, or x.

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.
