Answer:
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.

Density = [Mass/Volume]
Here we have been given the dimensions of the object.
Volume = Height * Width * Length
Volume = 
=
Now we can substitute the Mass and the Volume to the density equation.
Density = [Mass/Volume]
=
= grams per cubic centimeter. (Rounded off to 4th decimal)
