A parking garage allows users to park the first hour free and then charges $2.50 for each additional hour or fraction of an hour
Snowcat [4.5K]

The first hour is free, and the rest charges is $2.50


Let x be the time.

Let y be the total


Your equation will look like


When x < 2, y = 0

When x > 1, y = $2.50(x)


So:


1 < x < ∞ for hours, then equation will look like:

y = total amount

$2.50 is cost (remember that the first hour is for free, and so you subtract $2.50 from the total.


$2.50x - $2.50 = y should be your equation.


hope this helps

One day you bike for 30 miles 10 cool down at a rate of 0.25 miles/minute. The total distance you bike is 35 miles. How many min
tatyana61 [14]
To determine the length of time it would took for the biker to cool down, we need the rate that would relate the distance he traveled to cool down per units of time. For this problem, the rate is given as 0.25 miles per minute. So, we simply divide the total distance he traveled with this rate. We calculate as follows:

time to cool down = distance / rate
time to cool down = 35 miles / 0.25 miles / minute
time to cool down = 140 minutes or 2 hrs and 20 minutes

Therefore, the biker would need to cool down for about 2 hrs and 20 minutes if he traveled for 35 miles.
