Fast pls solve this question correctly in 5 min pls I will give u like for sure Vs
An espresso stand finds that its weekly profit is a function of the price, z, it charges per cup. If z is in dollars, the weekly profit is
P(x)= -2900z²+8700z-4815.75 dollars.
=
(a) The espresso stand's current price is $1.8 for each cup of espresso. This means their current weekly profit is $ (round to the
nearest cent).
(b) The maximum possible weekly profit is $-5511.75 (round to the nearest cent and do not include any commas in your answer).
(c) What is the price per cup that will produce the maximum profit?
The espresso stand should reduce their price by
$01
cents and choose a price of $
for each cup in order to maximize profit.
