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 What is the price for 10 balls, not including the entrance fee?

the price for 10 balls is $8.00

Step-by-step explanation:

Given;

The total price function;

P = 0.80n + 5.50

Total price P = price of balls(variable cost) V+ entrance fee(fixed) F

So,

price of balls(variable cost) V(n) = 0.80n

entrance fee(fixed) F = 5.50

The price for 10 balls, not including the entrance fee is

V(n) = 0.80n

n = 10

Substituting the given values;

V(10) = 0.80(10) = $8.00

the price for 10 balls is $8.00

a triangle's   full angle is 180 degrees so 180 - 156 = 24. 24/2=12
