A caterer charges $120 to cater a party plus $5 per person. Assume the cost, y , is a linear function of the number of x people. Write an equation in slope-intercept form for this function. What does the slope represent? How much would a party for 40 people cost?

Answer:

5x + 120 = y

40 = x

5(40) + 120 = y

200 + 120 = y

320 = y

So the total cost is $320

The linear equation is

y = 5x + 120

Answer:

  • Part A y = 5x  +  120
  • Part B 320 dollars.

Step-by-step explanation:

y= 5x + 120

The slope represents the cost per person.

Let x = 40 people.

  • y = 5x + 120
  • y = 5*40 + 120
  • y = 200 + 120
  • y = 320

The cost of a party of 40 people would be 320 dollars
