For his birthday, Jerry wants to invite a bunch of friends to go bowling. There are two bowling alleys near his house, Strike Guys & Gutter Ball. The costs for birthday parties at both are shown below.
Strike Guys
Gutter Ball
$45 set-up fee
$150 for up to 15 people
$10 for each person thereafter
$7 per person
.
Benny used this information to create the expressions below, where x is the number of people at the party:
Strike Guys: 150 + 10(x - 15)
Gutter Ball: 45 + 7x
2) Based on his math, Jerry told his mother, "If we invite fewer than 30 people to the party, the Strike Guys cost less. Since
I'm inviting 20 people, I think Strike Guys is the better deal." Is Jerry's argument reasonable? Find the cost for each
company if Jerry invites 20 people. Explain to Jerry's mother which bowling alley is the best deal for 20 people.
