Question

A paintball court charges an initial entrance fee plus a fixed price per ball.

The variable p models the total price (in dollars) as a function of n the number of balls used. p=0.80n+5.50
What is the entrance fee $[_______]

Answer 1

Answer:

The entrance fee is actually quite obvious in the formula. But to find it mathematically we can use an example, so say we are renting the court and asking for 0 balls. 0 x 0.8 = 0 added to 5.50 makes the total cost 5.50. This obviously makes the entrance fee 5.50.

Now you could have easily seen that in the formula, the addition of 5.50 to any price is a fixed value and does not change regardless of the amount of balls rented, just like the initial entrance fee is fixed and does not change regardless of the number of rented ball

Step-by-step explanation:
