Maybe you missed to add the complete question. After a little research I was able to find the complete question which is as follows:
<em>''The cost y(in dollars) to provide food for guests at a dinner party is proportional to the number x of guests attending the party. It costs $30 to provide food for 4 guests. a. Write an equation that represents the situation. b. Interpret the slope. c. How much does it cost to provide food for 10 guests?'' </em>
So, I am solving based on this complete question.
Answer:
Please check the explanation.
Step-by-step explanation:
<em>a. Write an equation that represents the situation. </em>
As the cost and the number of guests are proportional.
So the equation of the form
Plug in the values y = 30 and x = 4 to find m
30 = m (4)
m = 30/4
= 7.5
Now, substituting m = 7.5 in the equation y=mx
<em>b) Interpreting Slope</em>
Given that the units for y are dollars, and the units for x are guests.
Thus, the slope 7.5 means it costs $7.5 per guest.
<em>c) How much does it cost to provide food for 10 guests?'' </em>
We know the equation
put x = 10
y = 7.5(10)
y = $75
Thus, it costs 75 dollars for 10 guests.
