The right answer is Option D.

Step-by-step explanation:

Let,

Kyle's money = x

Hayden's money = y

Jeremy's money = z

According to statements;

Kyle has three times as much money in his savings account as Hayden.

x = 3y Eqn 1

Hayden has twice as much money in his savings account as Jeremy.

z = 2y Eqn 2

Combined Kyle, Hayden, and Jeremy have a total of $612.

x+y+z=612 Eqn 3

Putting value of x and z from Eqn 1 and 2 in Eqn 3

$3y+y+2y=612\\6y=612$

Dividing both sides by 6

$\frac{6y}{6}=\frac{612}{6}\\y=102$

Putting in Eqn 1;

$x=3(102)\\x=306$

Kyle has $306 in his account.

The right answer is Option D.

<h3>How to calculate total money spent ?</h3>

To calculate total money spent we have to add all the money we spent on all things.

Given that Ted has $55. 00 in his pocket.

(i)

two books for $29. 95 each

Money needed for 2 books = $2\times 29.95=59.9$

So Ted is not able to purchase 2 books

(ii) headphones for $29. 99 and a portable speaker set for $30. 95

Money needed for headphones and portable speaker = 29.99+30.95=60.94

So Ted is not able to purchase headphones and portable speaker

(iii) an MP3 player for $35. 99 and a $20. 00 gift card for downloading music

Money needed for MP3 player and gift card= 35.99+20.00=55.99

So Ted is not able to purchase MP3 player and gift card

(iv) three books for $16. 99 each.

Money needed for 3 books = $3\times16.99$ =50.97

So ted is able to purchase these three books .

If Ted has $55. 00 in his pocket then out of two books for $29. 95 each headphones for $29. 99 and a portable speaker set for $30. 95 an MP3 player for $35. 99 and a $20. 00 gift card for downloading music three books for $16. 99 each he can purchase three books for $16. 99 each.
