I'm stuck on bQuote:
When bicycles are sold for $300 each, a cycle store can sell 70 in a season. For every $25 increase in the price, the number sold drops by 10.
a) Represent the sales revenue as a function of the price.
b)The total sales revenue is $17,500. How many bicycles were sold? What is the price of one bicycle?
c) What range of prices will give a sales revenue that exceeds $18,000?
n= number of bikes
Price| Number of Bikes sold
300 | 70
325 | 60
350 | 50
So find the slope
Plug that into y=mx+b
So that means the function to find n(number of bicycles sold) is
Since Revenue is then part a is which simplifies to
So to solve part b?(Speechless)
