David received $50 dollars for working at his father’s store. he spent $20 dollars at the movies, and $10 dollars buying comic books. after buying $5 worth of candy, he saved the rest. what is the ratio of the amount of money david spent to the amount that david saved?

Total amount of money received by David for working at his father's store = $50
Amount of money spent by David at the movies = $20
Amount of money spent by David buying comics books = $10
Amount of money spent by David buying candy = $5
Then
Total amount spent by David = (20 + 10 + 5) dollars
                                               = 35 dollars
Amount of money saved by David = (50 - 35 ) dollars
                                                       = 15 dollars
So
The ratio of the amount of money David
spent to the amount of money David saved = 35:15
                                                                      = 7:3
So the ratio of the amount of money David spent to the amount of money David saved is 7:3

The answer is all about the number 4
