Determine the smallest amount of money for which the check could have been written for.
:
I spent considerable time on this and found it can not out right as written unless I say he spent 58 cents instead of 68 cents.
:
let a = original number of dollars
let b = original number of cents
:
2(a + .01b) = b + .01a - .58
2a + .02b = b + .01a - .58
2a - .01a + .02b - b = -.58
1.99a - .98b = -.58
- .98b = - 1.99a - .58
multiply by -100
98b = 199a + 58
b =
the only integer solution to this is:
a = 46, then b = 94
The original check was $46.94
The teller gave him $94.46, he spent .58 so he had $93.88
This is twice $46.94
