Answer:
Skyhigh : 40 friends
Jump it up : 90 friends
Step-by-step explanation:
Given that :
Total amount available to spend = $250
JUMP IT UP:
Party set up fee = $70
Amount paid per person = $2
Number of friends = 90
SKY HIGH:
Party set up fee = $50
Amount paid per person = $5
Number of friends = 40
INEQUALITY :
Party setup fee + amount per person * Number of persons ≤ available amount to spend
SKY HIGH:
50 + 5x ≤ 250
5x ≤ 250 - 50
5x ≤ 200
x ≤ 200/5
x ≤ 40
Hence,
Skyhigh = 90 friends
JUMP IT UP:
70 + 2x ≤ 250
2x ≤ 250 - 70
2x ≤ 180
x ≤ 180/2
x ≤ 90
Jump it up = 90
