To play indoor soccer at the Sun Oaks Club, you must pay a $100 membership
sukhopar [10]

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

f(t)=100+10t

So, the required function is f(t)=100+10t.

Now, if the hourly rate were halved. Then,

Hourly rate = \$ \dfrac{10}{2} = \$ 5

So, total variable cost is $5t and total cost function is

g(t)=100+5t

So, the required function is g(t)=100+5t.

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
