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

AysviL [449]

ANSWER

The correct answer is A

EXPLANATION

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

$=\frac{1950}{7941}$

$=0.2456$

$ $\approx 0.30$

C. not all birds fly.
When using _:_, you are contrasting two things so, you are putting a argument to go against the other side.
Not all birds can fly is going against All birds can fly.
