Answer:

The cost is a fixed $2, plus $3.25 for any additional hour.

Then if you rent it for x hours, the cost is:

c(x) = $2 + $3.25*x

Is this situation continuous or discrete?

Yes, it is discrete, because x is "the number of hours"

so if you rent it for 1.30 hours, they will say "ok, this is equivalent to two hours".

This means that while the values of x are continuous, the possible costs are:

{$2, $2 + $3.25, $2 + 2*$3.25, ....}

Which is a discrete set.

Then the sign for 1 to 5 hours will be:

1 hour ---------- $2 + $3.25 = $5.25

2 hours -------- $2 + 2*$3.25 = $8.50

3 hours--------- $2 + 3*$3.25 = $11.75

4 hours--------- $2 + 4*$3.25 =  $15

5 hours -------- $2 + 5*$3.25 = $18.25

In the other park the cost is only $4 for each hour (no fixed cost) then the total cost for x hours is:

c(x) = $4*x

Now, which option is better?

If we look at the costs for different numbers of hours for this other equation, we have:

1 hour ----- $4

2 hours ---- 2*$4 = $8

3 hours ----- 3*$4 = $12

4 hours ------ 4*$4 = $16

Then: if you want to skate 2 hours or less, Skate City is cheaper, if you want to skate more than that, kate Days is cheaper.

This happens because the first one has a smaller slope, meaning that is larger at first, but as x grows the price does not grow as much as in Skate City

Hey, could you please answer this question? My time is running out. A bicycle rental shop has a two tier pricing system based on
erastova [34]

Answer:

3.93 per hour

Step-by-step explanation:

The first 4 hours is at 20 hours / 4 hours  or 5 dollars an hours

The second  line has a slope of 2.50 dollars an hour

But there is also a surcharge when you go over 4 hours

That is a 5 dollar flat rate at 4 hours

Assuming that we do not include the flat rate in the hourly calculation

4 hours * 5 dollar + 3 hours * 2.50 = 20+7.50

27.50 is the hourly charge

Divide by 7 hours

3.928571429

3.93 per hour
