Answer:
Company A: 
Company B: 
Step-by-step explanation:
The initial fee is the y-intercept, as that is the cost at x = 0, or the cost before any time has passed. Afterwards, the rate the cost increases is the slope.
Linear equation in slope-intercept form:
where m is the slope and b is the y-intercept.
Company A charges $50 up front and $40 per hour afterwards, so the equation would be:
Company B charges $25 up front and $50 per hour, so:
I believe the correct answer would be 150 pages
If ur answer (in this case, its 52) is greater than 0, then there are two real solutions.
If it is equal to 0, then there is one solution
And if it is less than 0, there are no real solutions.
Therefore, there are 2 solutions.
Let e be the minimum number of workers needed.
e(100-3)/100≥215
97e/100≥215
97e≥21500
e≥21500/97
e≥221.6
Since the number of employees must be an integer...
e≥222
So the minimum number of employees needed is 222.
