Jack's Savings
Jack donates 5% of his household income to various charities. He spends 5% of his income on gas. He spends 10% of his income on food. Another 20% of his income goes to pay his utilities. He spends another 20% on his house payment. He spends another 15% on his credit cards bills. He spends 15% on his income on his truck payment. He also spends 8% on his Health club member ship. If Jack makes $44,000 a year, how much will he be putting back in his savings account each month, if he is only wanting to deposit 35% of what's left after all his expenses? (The percentages were figured for one calendar year.)
Answer
$25.675% Charities
5% Gas
10% Food
20% Utilities
20% House payment
15% Credit cards
15% Truck payment
8% Health club
Total expenses = 98% (of his total yearly income)
$44,000 x 98% = $43,120 (total spent on expenses)
$44,000 - $43,120 = $880 (total left after expenses)
$880 x 35% = $308.00 (total deposited in his Saving account during 1 year)
$308.00 divided by 12 = $25.67 (amount deposited in his account every month)

I wasn’t for sure if this one was worth submitting or not. I'm finding out I'm not to good at writing these Math Teasers.
i think it wuz worth submitting if the editors put it on the website. in my opinion, this teaser wuz good. ez, but good...8^)
Since you ask, I think that perhaps this
teaser might be interesting to some of the
younger readers, but it's too straightforward
a calculation for those of us that are older.
In general, I think if you can just punch
the numbers into a simple calculator and compute
the answer, then you have a problem, not a puzzle.
I think a good math puzzle should involve some cleverness or thought
in how you set up the problem in order to solve it.
I wish you well in creating future puzzles.

Well, you know it got me in that I forgot to divide by 12. Good one nonetheless. Even for one of us "older guys".
