You go furniture shopping and see a sign advertising: 25% off all dining furniture 30% off living room furniture 35% off bed sets You find a couch that you'd like for your living room, marked at $765. Estimate the cost of the couch after the discount (don't do an exact calculation). Describe your estimation strategy. In other words, don't just say something like "about $300"- describe the process you used to come up with that estimate. Note: There is not a "right" answer here - there are a lot of ways to come up with reasonable estimates, and not everyone's estimate will be the same (though they should be fairly close).

see below

Step-by-step explanation:

The couch is 765

Rounding its price to 750 dollars

We get 30 percent off which means we pay 70 percent of the value

take 750 time 7 = 5250 and move the decimal one place to the left  since we multiplied by 7 and not .7

525

The cost of the couch is around 525 dollars

The actual sale price is

765 * .7 =535.50  so our estimate is a little low

answer

explanation

the area of a circle is calculated using the formula

or

we can use any of the above formulae to calculate the required. preferably, let us use the latter since the diameter is

we substitute the diameter into the formula to get:

this is the exact value for the area of the circle.

the correct answer is a

i would have to say it is c.
