Stan is buying party favors for his birthday party. There will be 20 guests at his party. Party favors come in packages of 6. What is the least number of packages he needs to buy so that all his guests get a party favor?

The minimum package Stan need to buy  so that all his guests get a party favor is 4 packages.

Step-by-step explanation:

Given;

total number of guest in the party = 20

number of party favor needed = 20 party favors

1 package = 6 party favor

then, 2 package = 12 party favor

         3 package = 18 party favor

         4 package = 24 party favor

24 party favor will serve all the guest.

Therefore, the minimum package Stan need to buy  so that all his guests get a party favor is 4 packages.

step-by-step explanation:

-8/2y-8=5/y+4-7y+8/y^2-16

we move all terms to the left:

-8/2y-8-(5/y+4-7y+8/y^2-16)=0

we can not solve this equation
