Answer:
C. 1/4
Step-by-step explanation:
Step 1
Make the fraction denominators the same!
1/2 will become 4/8 over here, and 2/8 is already good!
Step 2
Subtract the new fractions!
4/8 - 2/8 is easy! It's 2/8
Step 3
Simplify the answer (2/8)
2/8 will become 1/4 when simplified
<h2>Hence, the final answer is 1/4</h2>
or C

Step-by-step explanation:
10a-15b
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.
