Answer: a=100 and b=5
Step-by-step explanation:
Given: A school typically sells 500 yearbooks each year for $50 each.
The economics class discovers that they can sell 100 more yearbooks for every $5 decrease in price.
Let x represents the number of $5 decreases in price.
Then the new price (in dollars)=50-5x
Total yearbook sold=500+100x
If the revenue for yearbook sales is equal to the number of yearbooks sold times the price of the yearbook.
Then the revenue function will be [tex]R(X)=(500+100x)(50-5x)[/tex]
On comparing this with the given revenue expression we get
a=100 and b=5.
In this exercise we have to calculate the values โโof A and B, so we have to:
[tex]A=100\\B=5[/tex]
Since the equation is:
[tex]R(X)=(500+ax)(50-bx)[/tex]
And the following information was given:
- A school typically sells 500 yearbooks each year for $50 each.
- The economics class discovers that they can sell 100 more yearbooks for every $5 decrease in price.
So knowing that by increasing 100 more books sold this is equal to A and the decrease in value is going to be equal to b.
[tex]R(X)=(500+100x)(50-5x)[/tex]
