My Grocery shopping was exactly $40.00

Thanks for making me spend like 30 seconds of my life reviewing someone's grocery receipt. We're really starting to stretch the mildy part of mildly interesting, but apparently I'm here for it.

Good & Gather, one of Target's store brands, in case anyone was actually curious.

Arizona, Groceries aren't taxed here.

I don't know where OP is, but here in Massachusetts, we have no sales tax on groceries:

NE has the same no-grocery tax rule. A handful of states have no sales tax in general (I believe SD and either NH or VT for example) and many, if not all, won't tax groceries purchased with whatever food stamps are called in the respective state

No sales tax in Oregon, but income taxes are rough. My friend moved across the river to Vancouver, WA and makes ~$50k more a year from tax savings.

Yeah I'm on the edge of my seat here. I demand a refund.

OP certainly hit this target.

I was thinking OP lived in some libertarian utopia.

9*10=90 Ends in 0.

Literally any time you do anything like 10 × n it will end in a zero. All multiples of ten end in zero.

Same with 100 × n: it will always end with 00.

Wait until you find out 0,99... (repeating nines forever) equals 1

Ten number ending in 9 is essentially the same as those same ten numbers but ending in zero plus ten nines.

$1.19 = $1.10 + 0.09

$1.19 + $1.69 = $1.10 + $1.60 + (2 * 0.09)

Since there were 10 items, each ending in a 9, that's the same as 9 times 10, or in this case $0.09 * 10. Every time you multiply by 10 you end up with a zero on the end.

In a base 10 system multiplying by 10 basically shifts all the digits over by 1 and adds a zero to the end. Whatever was in the 10s spot goes in the 100s spot. Whatever was in the 100s spot goes in the 1000s spot, and so on.

So, if you buy 10 items with a 9 at the end of their price, you'll always end up with a zero in the cents spot. If you buy 100 items like that, your total will be in dollars with zero cents.

What's more impressive here is that so many of the other digits ended up as zero when there was no pattern. Ten items ending in '9' means that you carry over a '9' to the next column, but to get that to be zero means the sum of all the tens (of cents) digits needed to end up in a 1.

1 + 6 + 9 + 4 + 9 + 9 + 6 + 6 + 2 + 9 = 61

And to get to exactly 40, the dollars digits needed to match that 6 plus 1 carried over (1 + 9), so they needed to end in 3 (or to be 33 exactly for the total to be 40):

1 + 1 + 6 + 5 + 3 + 3 + 5 + 5 + 3 + 1 = 33

Ignoring the fact that grocery stores suck and price things ending in 9 all the time, it's a 1/10 shot to get the cents digit to end up as a zero, a 1/10 shot for the hundreds to end up as zero, and 1/10 for the dollars digit to end up as a zero. OP just used up a lifetime of luck for a 1/1000 occurrence.

To OP: GG Cheese!

They're oatmeal raisin from the bakery. They're pretty good.
