Answer :
Let y be the number of people that will attend the conference as a function of x. The given information tells us that when x = 0 (the admission price is $400), y = 1000. Additionally, for each $5 reduction in price, an additional 20 people will attend.
We can express this relationship as a function as follows:
- y = 1000 + 20x
This function tells us that the number of people that will attend the conference is equal to 1000, plus an additional 20 people for each $5 reduction in price (represented by the variable x).
For example, if the admission price is reduced by $10 (x = 2), the number of people that will attend the conference is given by:
y = 1000 + 20(2)
y = 1000 + 40
y = 1040
So, if the admission price is reduced by $10, 1040 people will attend the conference.
