Answer:
654 grams
Step-by-step explanation:
When you set up this equation you want the number of grams you start with, 2616, and the factor by which it is decreasing, which is half, or 1/2. Because the half life is 11 days, but you want to find the amount left over after 22 days, you can make 22/11 as the exponent on the 1/2. The equation should look like this : 2616(1/2)^22/11. With these kinds of equations you always want to multiply the starting value by the factor of increase/decrease, and raise that factor to the time eclipsed divided by the set time(like the 11 day half life).
<span>for that, what you need is a calculator... like say a TI(texas instruments) 83 or 83plus or higher, will do regressions, if you have an android device like a phone or tablet, you can also get an app from the play store "Andie's graph", is a TI calculator emulator, it works just like the calculator itself, you'd only need the ROM
</span><span>that said, you can also use some online calculators for that.
</span>
<span>I could give you a direct link to one, but this site has issues with links, if you do a quick search in google for "keisan exponential regression calculator", it should be the first link, is from the Casio site.
</span>
<span>you could do regressions in a spreadsheet as well.... you could check online for an "addin" or "extension", if you use MS Excel, pretty sure there are some addins for regressions.
</span>
if I recall correctly, Excel does regressions natively, but the addins are just frontends, is all, just some added interfacing.
anyhow, if you have an Android device Andie Graph works peachy, I have an 83plus, 84, 86 in it, they all work just like my old TI83plus.
there's also an app in the play store called Graph89, is an emulator for a TI89, the same you need a tiny little file, and texas instruments provides them, have also, works peachy too.

Complete question;
Andy, who loves to cook, makes apple cobbler for his family. The recipe (serves 6) calls for 4 3/4 pounds of apples, 5 1/4 cups of flour, 1/6 cup of margarine, 2 7/8 cups of sugar, and 2 teaspoons of cinnamon. Since guests are coming, Andy wants to make a cobbler that will serve 15 (or increase the recipe 2 1/2 times). How much of each ingredient should Andy use?
Answer:
To serve 15, number of ingredients Andy should use =
Apples = 11 7/8 pounds
Flour = 13 1/8 cups
Margarine = 5/12 cups
Sugar = 7 3/16 cups
Cinnamon = 5 teaspoons.
Step-by-step explanation:
The recipe (serves 6) calls for 4 3/4 pounds of apples, 5 1/4 cups of flour, 1/6 cup of margarine, 2 7/8 cups of sugar, and 2 teaspoons of cinnamon. Since guests are coming, Andy wants to make a cobbler that will serve 15 (or increase the recipe 2 1/2 times). How much of each ingredient should Andy use?
For Apples
Serving for 6 = 4 3/4 pounds of apples
Serving for 15 =
= 15 × 4 3/4 pounds/6
= 11 7/8 pounds of apples
For flour
6 servings = 5 1/4 cups of flour,
15 servings =
15 × 5 1/4 cups/6
= 13 1/8 cups of flour
For Margarine
6 servings = 1/6 cups of margarine
15 servings =
= 15 × 1/6 cups/6
= 5/12 cups of margarine
For Sugar
6 servings = 2 7/8 cups of sugar
15 servings =
15 × 2 7/8 cups/6
= 7 3/16 cups of sugar
For Cinnamon
6 servings = 2 teaspoons of cinnamon
15 servings =
15 × 2/6
= 5 teaspoons
Therefore, to serve 15, number of ingredients Andy should use =
Apples = 11 7/8 pounds
Flour = 13 1/8 cups
Margarine = 5/12 cups
Sugar = 7 3/16 cups
Cinnamon = 5 teaspoons.
