To make a positive profit p(x)>0 we need to make:

Now we solve this for x:

We have:
a = -2
b = 7
c = -3
We will use formula for quadratic equation:

We got two solutions. One is fraction other is whole number. We will not consider fraction because the amount of muffins sold must be whole number. So our solution is:
x>3
Answer:
it ix 23 then 43
Step-by-step explanation:
Answer:
The cost of 4 medium pizzas:
4 (x - 3)
Step-by-step explanation:
#3
x = the cost of a large pizza
medium pizza costs $3 less than a large pizza. So it's x - 3
If 4 medium pizzas then it will be: 4 (x - 3)
An=3*(4^(n-1)) is the explicit
the recursive is <span>t_n = 4 * t_(n-1)</span>
One way you can rename it is by putting it into word form. Word form would be thirty thousand, but I don't know another way on how to express it.
