Answer: $1.75
Solve for:
What price would result in the most revenue?
Step-by-step explanation:
Let the price of one donut = 1 + 0.05x
Let the # of donuts he can sell = 500 - 10x
Revenue,
[tex]R(x) = (1 + 0.05x)(500 - 10x)[/tex]
[tex]R(x) = 500 - 10x + 25x - 0.5x^2[/tex]
[tex]R(x) = -10 + 25-0.5(2x)[/tex]
[tex]= 15-x\\x=15[/tex]
Revenue is maxed when x = 15
When the revenue is maxed,
[tex]Price = 1 + 0.05(15)\\=1 + 0.75\\=1.75[/tex]
Therefore the best price for this scenario is $1.75
