Let's say 1000 dollars was spent on all of these. That would mean 170 dollars and 240 were spent on food and entertainment respectivly. If we want to see how much of the total cost was spent on these things, we would have to add them and divide them by 1000, so:
[tex] \frac{170+240}{1000}=\frac{410}{1000}=frac{41}{100}[/tex]
