Afootball team plays in a large stadium. with a ticket price of $15, the average attendance at recent games has been 20,000. a market survey indicates that for each $1 increase in the ticket price, attendance decreases by 400 people. express the revenue from a baseball game, r, as a function of the ticket price, x.

R(x) = (20,000 - 400x)(15+x)

Step-by-step explanation:

Given,

The original price of each ticket = $ 15,

Original number of people or attendance = 20,000

Let the price of each ticket is increased by x times of $ 1,

That is, new price of each ticket = ( 15 + x ) dollars,

∵ for each $1 increase in the ticket price, attendance decreases by 400 people,

So, the new number of people = 20,000 - 400x

Since,

Revenue = number of people × price of each ticket

⇒ R(x) = (20,000 - 400x)(15+x)

Which is the required function.

step-by-step explanation:

answer: the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step-by-step explanation:

the given rate of interest i= 85%

in calculating the monthly payment for a loan with an interest rate compounded monthly, the value of the interest rate per period we use in the formula must be in decimal form.

to convert it in decimal, we divide it by 100, we get

hence, the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.
