a.

Answer to Problem 18PPS
Explanation of Solution
Given information:
Admission price is $15
620 people visit per day
Each $0.50 decrease in the price result will 40 additional visitors
Calculation:
Admission price in $
People visit per day
Each $0.50 decrease in the price result will 40 additional visitors
Let x be the number of $0.50 decrease in the price
Then function to represent the museum's admission price
b.
To write a function to represent the number of visitors per day.
b.

620 people visit per day
Each $0.50 decrease in the price result will 40 additional visitors
Calculation:
Admission price in $
People visit per day
Each $0.50 decrease in the price result will 40 additional visitors Let x be the number of $0.50 decrease in the price
Then function to represent the museum's admission price
Then function to represent the number of visitors per day
Then revenue per day
Substituting value of price and number of visitors function in above
Obtained,
On solving,
d.

Answer to Problem 18PPS
Explanation of Solution
Given information:
Admission price is $15
620 people visit per day
Each $0.50 decrease in the price result will 40 additional visitors
If admission price become $13
Calculation:
Admission price in $
People visit per day
Each $0.50 decrease in the price result will 40 additional visitors
Let x be the number of $0.50 decrease in the price
Then revenue per day when price become $13
when price become $13
Then
Substituting value of x in revenule function
On solving,
