Given that:
Membership feet to play indoor soccer at the Sun Oaks Club = $100
Hourly rate = $10
To find:
The function f represents the cost of playing soccer at Sun Oaks.
Here, fixed cost is $100.
Let the number of hours of playing be t. So, total variable cost is $10t.
Total cost = Fixed cost + Variable cost

So, the required function is
.
Now, if the hourly rate were halved. Then,
Hourly rate 
So, total variable cost is $5t and total cost function is

So, the required function is
.
What's up? answer is $4.05
explained:
10% of $45 would be $4.50
4.50x4= 18
45-18= 27
10% of 27 is $2.70 half of $2.70 is $1.35
$2.70 + $1.35 = $4.05
you spent $4.05 on the snack

Answer:
n = - 10
Step-by-step explanation:
10(-3n + 8) = 380
-30n + 80 = 380
80 - 380 = 30n
30n = - 300
n = - 300 : 30
n = - 10
