Deductible

The deductible is the amount of money you will pay in an insurance claim before the company starts paying you insurance coverage .

As given

She had medical expenses of $18,240.00.

Amount becomes after deducting deductible = $18,240 -  $250

                                                                                   = $17990

Sue need 1 1/4 cups of flour for a batch of cookies.
MA_775_DIABLO [31]

4 batches: 1 1/4 + 1 1/4 + 1 1/4 + 1 1/4 = 4 4/4 = 5

6 batches: 1 1/4 + 1 1/4 + 1 1/4 + 1 1/4 + 1 1/4 + 1 1/4 = 6 6/4 = 7 1/2

7 batches: 1 1/4 + 1 1/4 + 1 1/4 + 1 1/4 + 1 1/4 + 1 1/4 + 1 1/4 = 7 7/4 = 8 3/4

8 batches: 1 1/4 + 1 1/4 + 1 1/4 + 1 1/4 + 1 1/4 + 1 1/4 + 1 1/4 + 1 1/4 = 8 8/4 = 10

The answer is C because 8 batches needs 10 cups of flour, and 7 batches is closest to 9 cups than 6 batches.

You can also look at it like this:

1 1/4c ≤ 9 (c is # of cups)

Or you could have multiplied 4, 6, 7, 8 to 1 1/4 or 1.25

Formula of a circumference:

2πr

In this case

pi is 3.14 and your radius is 6 and 2 is just 2.
