Hello :D
To find out the original price you have to do:
$36.64 + $2.18 = $38.82
Original price = $38.82
X = short section of rope
4x = longer section of rope
x + 4x = 25
5x = 25
x = 5
…or in other words the shorter piece of rope is 5 feet long
It would be 60.
a(b)^x
Since a/ 60 would represent initial value.
