Answer:

2

Step-by-step explanation:

Find the greatest common factor of 8, 18, and 70.

Since we are looking for the Greatest Common Factor of the numbers given, we begin by factoring the numbers. It is usually easiest to start with the smallest number. Also, if there is a number that has obvious factors. In our case,  satisfies both of these:

8=2⋅2⋅2 In fact,

8 only has one unique factor! If there is to be a common factor (other than

1 ) it must be

2. We now need to check that both

18 and 70 have 2 as a factor:

18=2⋅9

70=2⋅35 Therefore, 2 is the GCF of 8, 18 and 70.

Leona purchased a $1,000 bond having a quoted price of 99.875. She had to pay a 5.5% brokerage fee (of the selling price). What
Ede4ka [16]

Answer:

None of these choices are correct.

Step-by-step explanation:

The quoted value of 99.875, means that this bond is sold at 99.875%  of the face value and not at a price of  $99.875.

Therefore, calculate price;

Price = 0.99875 * 1000

Price = $998.75

Since brokerage fees is 5.5% of the selling price, Leona will pay additional cost to the quoted price making the total cost to be more than $998.75;

Brokerage fees = (0.055*998.75) = $54.93

Total cost = $998.75 +$54.93

= $1053.68

Therefore, none of the choices is correct.
