A caterer charges a $30 fee plus an additional $6.50 per person. She determines the total cost, C, for x people by using the equation shown above. How much will a party cost for 80 people?

$550

Step-by-step explanation:

In this question, we have to find how much a party would cost for 80 people.

We know that our equation is C = 6.50x + 30

"x" is the amount of people.

To found our answer, we would plug in 80 to "x" to find the total cost.

Solve:

C = 6.50(80) + 30

C = 520 + 30

C = 550

This means that the cost of the party for 80 people would be $550.

what are ur choices?

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
