I need help with question 30..

Aloiza [94]

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:

$\frac{170+240}{1000}=\frac{410}{1000}=frac{41}{100}$

The town library is raising money by selling old books for $2 each.Which equation can be used to find the amount of money raised

alexgriva [62]

Y=2x
y is the amount of money made from the sold books
x is the number of books that are sold (it is x because you don't know how many will be sold, so you have to account for all possibilities)
2x is because every book is sold for 2 dollars, so that mean x is multiplied by 2 to get y
