Using a system of equations, it is found that initially Ada has $0.385.
For the system, we have that the variables are:
- x is Ada's amount.
- y is Betty's amount.
- z is Chris's amount.
- w is David's amount.
$45 total, hence:
Ada <u>gets 2 from Betty</u>, hence:
<u>Chris triples</u> his money and <u>David's</u> money is <u>cut by half</u> four of them have the same amount, hence:
Then:
Solving for w, we find Ada's initial amount.
Initially, Ada has $0.385.
