Assuming no border or waste, 9m by 16 m translates to 29.52' x 52.49'.
use 32/8=4 sheets of plywood to cover the width on the 8' side.
For the length, use 52/4=13 pieces on the 4' side.  
This gives a total of 4*13=52 sheets.
The extra 0.49' x 29.52 can be covered using the extra from the last four sheets for the width.

Check: 
Area to be covered: 29.52*52.49=1550 sq. ft.
Area of plywood supplied = 52*4'x8'= 1664 sq. ft, > 1550 sq.ft.

Margaret uses a credit card with a 21.7% APR compounded monthly to pay for her car repairs totaling $692.77. She can pay $290 pe
igomit [66]

Answer:

B. $715.21

Step-by-step explanation:

Apparently, Margaret makes her first payment after she has incurred a finance charge on the amount.

At the end of the first month, the balance due is ...

... 692.77×(1 + 0.217/12) = 705.30

At the end of the second month, the balance due is ...

... (705.30 -290)×(1 +0.217/12) = 422.81

At the end of the third month, the balance due is ...

... (422.81 -290)×(1 +0.217/12) = 132.81

Margaret makes total payments of $290×2 +132.81 = $712.81

Of the choices listed, the best selection is ...

... B. $715.21

_____

<em>Comment on the answer choice</em>

The total $715.21 seems to also include a finance charge on the final payment amount. (It actually includes a charge on $132.72, which is slightly different from the final payment amount.) There will not be any such charge, so the <em>available answer choices are all in error</em>.

Actually, we expect the total cost to be closer to $702.25, because we expect that Margaret will make her first payment before any finance charges are incurred.

_____

You should ask your teacher to show you in detail how to work this problem.

At an aquarium, a shrimp if fed 1/5 gram of food each feeding and is fed 3 times each day. <em>What is the constant of proportionality and what does it tell us about the situation?</em>
