The formula lets you calculate how much you will get from each friend. So to see the total amount you will get you need to calculate what each friend will give you, then add the Base amount (Starting amount) plus the bonus amount if you get 10 or more.

So for 3 friends, you calculate with U=1, U-2, and U=3

U=1 - 200

U=2 - 400

U=3 - 600

So with three friends accepting you get 560+200+400+600=1760 food

For 800 friends than means calculating the forumla 800 times, replacing U wih the numbers 1-800.

At level 50 with 800 friends accepting you will get 64,537,510 food, or 2,010,380,400 gold.

200 friends - 4,049,680 food, 126,181,400 gold

400 friends - 16,155,260 food, 503,272,200 gold
