If you have a large bowl of salad (which is a whole 1) and your brother eats 1/3 of it before your friends come over, then you have:
1 - 1/3 = 2/3 of salad left
We don't know how many friends will come, so let's assume it's x of them who will visit you. In such case we have to divide 2/3 by x friends:
2/3 ÷ x =
= 2/3 * 1/x =
= 2/3x
Answer: Each friend will get 2/3x of the salad.

Step-by-step explanation:
Step-by-step explanation:
1. Buying 20 single candy bars at regular price
The regular price of one is 79 cents.
(# of bars) X (price per bar) = regular price
20 X 79 cents = 1580 cents
1580 cents = $15.80
2. Buying 20 bars in packs of 5
Each pack is $3
(# of packs) X (price per pack) = pack price
(20/5) X ($3) = pack price
4 X $3 = $12
3. Buying 20 bars at special price
For every 2 bought, 1 is free.
(Number of bars paid for) X (price per bar) = special price
(2(20/3)) X (0.79) = special price
14 X 0.79 = $11.06
Because for every 2 bars that are paid for, 1 is free, he pays for 14 bars and he gets the 21st free.
Andy's 20 regular priced candy bars are $15.80, bars in packs are $12, and bars at the special price is $11.06.
