Answer:
25
Step-by-step explanation:
From the given information;
Numbers of posters that can be printed in an hour = no of impression/hour × no of plate utilized in each impression.
= 1000x
Thus, the required number of hours it will take can be computed as:

cost per hour = 125
If each plate costs $20 to make, then the total number of plate will equal to 40x
∴
The total cost can be computed as:


At C'(x) = 0




x = 25


where; x = 25

C''(x) = 1.6
Thus, at x = 25, C'' > 0
As such, to minimize the cost, the printer needs to make 25 metal plates.
Answer:
1, 2, 3, 4, 6, 9, 12, 18, and 36
Answer:
132 square feet
Step-by-step explanation:
a+b/2*h
20+24/2*6=132
Answer:
<u>y = x/2</u>
Step-by-step explanation:
y = -x has a negative slope so cross this one out.
y = 2x has a steeper slope that would be above the black line so cross this one out
y = 0.001x has a slope that acends very slowly so cross this one out.
y = x/2 is the best match.
