PLEAS PLEASE PLEASE HELP!!

Using the given functions, it is found that:

  • Lower total cost at Jump-n-Play: 40, 64.
  • Lower total cost at Bounce house: 28, 8, 30.
  • Same total cost at both locations: 32.

<h3>What are the cost functions?</h3>

For n visits to Jump-n-play, the cost is:

J(n) = 189 + 3n.

For n visits to Bounce Word, the cost is:

B(n) = 125 + 5n.

Comparing them, we have that:

J(n) < B(n)

189 + 3n < 125 + 5n

64 < 2n

n > 32

Hence:

  • For less than 32 visits, the cost at Bounce World is lower.
  • For more than 32 visits, the cost at Jump-n-play is lower.

Hence:

  • Lower total cost at Jump-n-Play: 40, 64.
  • Lower total cost at Bounce house: 28, 8, 30.
  • Same total cost at both locations: 32.
