Roger is having a picnic for 78 guest he plans to serve each guest at least one hotdog if each package P contains eight hotdogs which inequality could be used to determine how many packages of hot dogs Roger will need to buy

Amount=number of hotdogs per package times number of packages

amount=8 times P

amount=8P

amount must be equal to or greater than 78 since each guest wants 1 at least

amount>78

8P>78

(if you wanted to solve, the answer is at least 10 packages)
