I got it for you........hold on let me write

Fuck man i been tryin flat out since u posted the info... I think as a start you need to turn the hours lasted into minutes... so the No Frills that last 12hrs 22mins would last for 732 mins. Same with the currency... Do it all in pennies instead of dollars.. It'll make matters easier... (i.e: $0.79 = 79)

I been fuckin wit it alot... i think the two numbers need to be divided somehow..

Really sorry i couldnt help nemore man.

work out the formula for the number of hours of battery power u get per dollar... thanx

Yo, answer, don't know if you still need help on this, but convert all the times into minutes, then divide the dollar amount by the minutes and you'll get something like .xx cents per minute.  If you multiply then by 60 that will be your cost per hour.

HHHEEELLLPPP!!!

it's easy...........     It's ....------>   Time / $ (time over dollars)

the tricky part is the conversion.........   first you gotta convert you Time to min.....

then it's just simple devision......


hope you get what i'm sayin'.....
