The answer is b because there is a negative in the exponent and the number needs to be a single digit and 54 is double digit. hope this helps!
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:
y=mx+b
Step-by-step explanation:
The formula to find the slope is y=mx+b
