Answer:

D. 56%

Step-by-step explanation:

For the fractions we will do:

\frac{wanted.outcome}{possible.outcomes}

      It depends on if he puts the first name back in, but I am going to asume Mr. Rosart does not, <em>so we will subtract one from the boys for the second pull</em>.

[Wanted over possible] \frac{14}{25}

[Dividing] 14 / 25 = 0.56

[Making a percent] .56 * 100 = 56%

<u />

Have a nice day!

     I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly. (ノ^∇^)

garri49 [273]

Answer:

Alice: 20 coins, Ben: 16 coins, and Carlos: 4 coins.

Step-by-step explanation:

We know that the dive results in 40 gold coins.

We know that:

Alice: $7,600 Ben: $5,900 Carlos: $1,400.

So they have $ 14900 in total.

Now we will divide that money by 40.

x=\frac{14900}{40}\\\\x=372.5

So 1 gold coin costs $ 372.5. Now we will calculate how much they can get for the money they have.

A=\frac{7600}{372.5}=20.4\\\\B=\frac{5900}{372.5}=15.8\\\\C=\frac{1400}{372.5}=3.75\\

We conclude that:

Alice: 20 coins, Ben: 16 coins, and Carlos: 4 coins.
