Shane returned from a trip to Las Vegas with $420, which was75% more money than he had at the beginning of the trip. How much money did Shane have at the beginning of his trip?

Shane had $240 at the beginning of his trip.

Step-by-step explanation:

Shane returned from a trip to Las Vegas with $420 and this is 75% more of at the beginning.

Let us assume the money he carried at the beginning of the trip was $x

At present he is having 75% more means total money he has = x+75% of x

This total amount is equal to $420

Therefore x +.75x = 420

x (1 +.75) = 420

1.75 x = 420

Now by dividing both sides by 1.75

x = 420:1.75

= $240

Therefore the amount he carried in the beginning of the trip is $240.
