    What formula will tell me on day n how much product has been used to date?

    Hi Abe21599,

    Glad you asked! Here goes...

    I used to get straight A's in algebra in high school and still use some of the basics but this problem eludes me. I need to find out how many mg. of product has been used to date? The amount increased per day remains constant at 2.14 mg. I know the numbers don't matter but this is what I'm dealing with:

    day 1 2.14 mg.
    day 2 4.28 mg.
    day 3 6.42 mg.
    day 3 8.56 mg.
    etc.

    For example, how much product (a powdered medicine, in this case) has been used by day 30? I have a constant (2.14 mg/day) and a variable (in this case, 30). Using simple addition, I can "inch" my way up to day 30 or if I knew the amount for day 29, I could simply add the constant (2.14) to it. But there's gotta be some type of equation that simply provides the accumulated total. Whaddaya think, Abe21599?

    How are you at math word problems?

    A party of three is traveling together and they stop for the night and want a single room because they have a limited budget. The manager tells them the night will cost them thirty bucks. Each member of the party coughs up a ten spot and they go to the room. The manager realizes it is Thursday and the three should have only been charged twenty-five dollars, instead of the weekend rate of thirty dollars. So, the manager calls over the bellhop and gives him five singles to return to the three men. On the way back he realizes that five singles can't be split up three ways. He knows the travelers don't know the actual room rate so he stuffs two bills into his pocket and gives one dollar back to each of the three travelers. Now that each traveler has been given one dollar back they each have paid nine dollars for the room. Nine times three is twenty-seven. The bellhop has two dollars. That brings the total to twenty-nine. Where is the missing dollar?
    Chris

    If you apply a rom or theme - backup first!
    If you don't know how to backup...Stop until you do.
    hint: I name my backups like this: sg6.0_20100428 or ss4.2_20100626 to easily find them later. rom and date.

    its in increments on 2.14 so its just P=2.14X

    where p is total product and x is the current day its on

    Would that give the total though? If I read the original problem correctly, on day 1, you have 2.14, on day 2 you have 4.28, but combined it is 6.42. It's been too long since my math days LOL.

    they paid 25 for the room (or at least should have). they were returned 3 dollars, bellhop kept 2. thats 30. 25 does not split evenly 3 ways so they paid 8 and come change (8.3333). they each paid this amount (x3 will equal 25) so it adds to 30.

    come on if ur gonna mess with me, its gonna have to be harder than that
