Question

A paintball court charges an initial entrance fee plus a fixed price per ball.
P represents the total price (in dollars) as a function of the number of balls used n.
P=0.80n+5.50
How much do 10 balls cost?

Answer 1

Answer : The cost of 10 balls will be, 13.5 dollars

Step-by-step explanation :

As we are given the following expression:

$P=0.80\times n+5.50$

where,

P = total price (in dollars)

n = number of balls used

Given:

n = number of balls used = 10

Now we have to determine the cost of 10 balls.

$P=0.80\times n+5.50$

$P=0.80\times (10)+5.50$

$P=8+5.50$

$P=13.5$

Thus, the cost of 10 balls will be, 13.5 dollars
