Question 1079284
.
<pre>
Let A = "How much Amy has in his wallet".

Then Shen has A+8 dollars, Ryan has 2*(A+8), according to the condition.

In total, they have 68 dollars, which gives you an equation

A + (A+8) + 2*(A+8) = 68.

Simplify it:

A + A + 8 + 2A + 16 = 68,

4A = 68 - 16 - 8,

4A = 44.


Can you complete from this point on your own ?
