Answer:

B - 2 hours

Step-by-step explanation:

find the rate for each scenario until you find one that matches.

for A 1 hour:

Ben charges (15.50×1hour) = 15.50

Cathie charges (9.25 × 1 hour) + 12.50 flat fee = 21.75

<u>THESE</u><u> </u><u>DO</u><u> </u><u>NOT</u><u> </u><u>MATCH</u>

so you do B 2 hours:

Ben charges 15.50× 2hours = 31

Cathie charges (9.25 × 2hours) + 12.50 flat fee = 31

<em><u>THESE</u></em><em><u> </u></em><em><u>MATCH</u></em><em><u> </u></em><em><u>SO</u></em><em><u> </u></em><em><u>THIS</u></em><em><u> </u></em><em><u>IS</u></em><em><u> </u></em><em><u>THE</u></em><em><u> </u></em><em><u>ANSWER</u></em>

If you continue like this for 3 hours and 4 hours the values don't match. <em><u>so the only answer is B</u></em><em><u>.</u></em>

One of your employees is bidding on a carpet installation job. They estimate that it will take 3 hours to install 12 square yard
Charra [1.4K]

Answer:

No, the bid is not correct.

Step-by-step explanation:

One of your employees is bidding on a carpet installation job.

They estimate that it will take 3 hours to install 12 square yards of carpeting.

we know that 1 square yard= 9 square foot.

12 square yard= 12×9 square foot=108 square foot

i.e. it takes 3 hours to carpet 108 square foot.

Hence time taken to carpet 1 square foot= \dfrac{3}{108} hour

Now the dimension of room is:

11' 6"× 12' 9" i.e. we convert both the units to foot as:

1 foot= 12 inch

11'6"=11+(6/12)=11.5  foot.

and 12'9"=12+(9/12)=12.75 foot.

Hence, dimension of room=11.5 foot×12.75 foot

Hence area of room=11.5×12.75=146.625 square foot.

Time to carpet 146.625 square foot=

\dfrac{3}{108}\times 146.625 hour

=4.0729 hour

But it is given that it takes 12.3 hours to install the carpet.

Hence, the calculations were wrong.
