i dont understand why the output is diffrent

Question

so i was working on the Kotlin parking fee code challenge at the end of control flow and i am not understanding why calculateFee outputs correct number but the calculateFeeSecond outputs wrong number can someone please help me understand Thanks here is the code below

fun calculateFee()
{
var hours = readLine()!!.toInt()
var total: Double = 0.0

if(hours <= 5)
{
total = hours * 1.0
}
else if(hours > 5 && hours < 24)
{
total = 5 + ((hours - 5) * 0.5)
}
else if(hours > 24)
{
total = 15 * (hours / 24) + 0.5 * (hours % 24)
}

println(total)

}

fun calculateFeeSecond()
{
var hours = readLine()!!.toInt()
var total: Double = 0.0

if(hours in 1..100)
{
if(hours == 5)
{
total = hours.toDouble() * 1
}
else if(hours > 5 && hours < 24)
{
total = 5 + ((hours.toDouble() - 5) * .5)
}
else
{
total = (hours / 24 * 15) + (0.5 * hours % 24)
}

}

println(total)

Answer 1

Your second if statement should be hours <= 5 not hours ==5

You need to use '%' operator before '*' because both operators have same precedence.
So, they are evaluated from left to right

total = (hours / 24 * 15) + ( hours % 24 * 0.5)

Answer 2

Thank you very much! Im sorry if that was a dumb question i wasnt thinking about the order of operations
