Question

Maureen wants to throw a surprise birthday party for her little brother. She contacts two trampoline parks, Jumping Jeb's and Hi-Skies, to ask how much they charge. She finds out that there is a proportional relationship between the number of guests at a party and the total amount of money each trampoline park charges. This table describes the cost of a party at Jumping Jeb's:
Jumping Jeb's
Guests Cost
5 $87.50
6 $105.00
8 $140.00
This equation describes the cost of a party at Hi-Skies. In the equation, y represents the cost in dollars of a party with x guests:
y=12x
Which company charges more per guest?
How much would that company charge for a party with 7 guests?
$

Answer 1

Jumping Jeb's charges more per guest.

Jumping Jeb's rate: 87.50 ÷ 5 = $17.50 per guest (checks with the other values).
Hi‑Skies rate: 12x → $12.00 per guest.

For 7 guests at Jumping Jeb's: 7 × 17.50 = $122.50.
