The tables below show running hours of three printers that produce greeting cards and the total number of greeting cards produce
AysviL [449]

<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


The total hours of printer B only

=50+50+30=130


Total number of cards produced over the three weeks


=7950+7800+9600=25350


We can use ratio and proportion to determine the total cards produce by printer B only.


415:25350


130:x


If less, more divides


x=\frac{130\times 25350}{415} \approx7941


Total cost of Printer B in 130 hours

$=130 \times 15=1950


The ink cost

=\frac{1950}{7941}


=0.2456


$\approx 0.30

to 2 decimal places
