Snap to It...
I snap my fingers now, in one second, I smap them again. I wait two seconds and snap them a third time. I wait 4 seconds before snapping them again. Then I wait eight, then sixteen, and the pattern continues. The interval between each snap doubles each time. How many times will I snap my fingers during the next year.
add them and then divide by two
The owner of a quick oil-change business charges $20 per oil change and has 40 customers per day. If each increase of $2 results in 2 fewer daily customers, what price should the owner charge (to the nearest $2) for an oil change if the income from this business is to be as great as possible?
