For this case we have a direct variation of the form:

Where "k" is the constant of proportionality. To find it, we use the following data:

Substituting:

Clearing the value of k:

Thus, the direct variation is given by:

For
we have:

Answer:
The value of the direct variation for
is: 
10000 pounds
1 ton is 2000 pound
5*2000 equals 10000
No because it has an ending it doesnt continue
Hey there! I'm happy to help!
Let's call the number of weeks w. Since we want their balances, to be equal, we can create an equation.
1000-55w=800-30w
Now we solve for w. We add 30w to both sides.
1000-25w=800
Subtract 1000 from both sides.
-25w=-200
Divide both sides by -25.
w=8
Therefore, Mark and Patricia will have the same amount of money in their savings accounts after 8 weeks.
Have a wonderful day! :D
