Step-by-step explanation:
The number of stickers John and Ken have in the end is 6 and 18 respectively.
<h3>How to write and solve equation?</h3>
let
- Ken stickers = x
- John stickers =3x
New stickers
x + x - 12 = 3x + 5x
2x - 12 = 8x
-12 = 8x - 6x
-12 = -2x
x = 12/2
x = 6
So,
Ken stickers = x
= 6 stickers
John stickers = 3x
= 3 × 6
= 12 stickers

Answer:
It will take Malik 23.157 additional hours of work to save total of $320 into his savings. Which is $220 of what he needs to match Linda.
Malik will work total 23.157 + 10.526hrs = 33.683 to save $320
Linda will work 45.714 hrs to save $320.
Step-by-step explanation:
Linda - $320 / 7hr rate = 45.714 hours worked to earn this amount.
Find out how many hours Malik worked to save $100 first.
$100 current savings divided by his hourly rate of $9.50 = 10.526 hours worked.
To find out how many hours Malik must work to have $320 in his account, we subtract what he has now $100 from what he needs $220 to match with Linda's $320. Next find how many hours it will take for Malik to save $220.
To get this take $220 / 9.5 hr rate which is what he gets paid per hour to get 23.157.
