Here it goes:

a. Because you have four blue marbles out of the 12 total marbles, the probability is 4/12. YOU MUST SIMPLIFY down to 1/3.

b. There are 12 marbles in the bag right now, and the probability is 4/12, you must add some marbles. 1/10 multiplied by 4 is 4/40. There are 4 blue marbles right now, and 40 minus the 12 there are right now is 38, so you would need to add 38 non-blue marbles.

Ratling [72]

Answer:

The selling price is $79.53 .

Step-by-step explanation:

Formula

$Profit\ percentage = \frac{Profit\times 100}{Cost\ price}$

Let us assume that the cost price be x .

As given

Judy Garland Electronics operate on a net-profile rate of 20% on its printer cables.

If the markup is $8.95 and the overhead is $4.31 .

Selling price = Cost price + Markup price + Overhead price

Putting all the values in the above

= x + 8.95 + 4.31

= x + 13.26

Profit = Selling price - Cost price

= x + 13.26 - x

= 13.26

Putting all the values in the above

$20 = \frac{13.26\times 100}{x}$

$x = \frac{13.26\times 100}{20}$

$x = \frac{1326\times 100}{20\times 100}$

$x = \frac{1326}{20}$

x = $ 66.3

Thus

Selling price = x + 13.26

= 66.3 + 13.26

= $ 79.53

Therefore the selling price is $79.53 .
