<u>ANSWER</u>
The correct answer is A
<u>EXPLANATION</u>
To find the ink cost of each card coming from printer B, we need to find the total cost from printer B and the total number of cards printed by Printer B.
The total hours of all the three printers over the three weeks
![=40+45+55+50+50+30+45+40+60=415](https://tex.z-dn.net/?f=%3D40%2B45%2B55%2B50%2B50%2B30%2B45%2B40%2B60%3D415)
The total hours of printer B only
![=50+50+30=130](https://tex.z-dn.net/?f=%3D50%2B50%2B30%3D130)
Total number of cards produced over the three weeks
![=7950+7800+9600=25350](https://tex.z-dn.net/?f=%3D7950%2B7800%2B9600%3D25350)
We can use ratio and proportion to determine the total cards produce by printer B only.
![415:25350](https://tex.z-dn.net/?f=415%3A25350)
![130:x](https://tex.z-dn.net/?f=130%3Ax)
If less, more divides
![x=\frac{130\times 25350}{415} \approx7941](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B130%5Ctimes%2025350%7D%7B415%7D%20%5Capprox7941)
Total cost of Printer B in 130 hours
$![=130 \times 15=1950](https://tex.z-dn.net/?f=%3D130%20%5Ctimes%2015%3D1950)
The ink cost
![=\frac{1950}{7941}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B1950%7D%7B7941%7D)
![=0.2456](https://tex.z-dn.net/?f=%3D0.2456)
$![\approx 0.30](https://tex.z-dn.net/?f=%5Capprox%200.30)
to 2 decimal places

Answer:
x=107,y=73 is ur answer
Step-by-step explanation:
let two angles be x & y
x-y=34(given)
x=34+y................1
x+y=180(supplementary)
putting the value of x
34+y+y=180
2y=180-34
y=146/2=73
:.y=73
putting the value of y in equation 1
x=34+73=107
:.x=107
