Question

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 if the number of books sold is known?Let x represent the number of books sold and y represent the amount of money raised.

Answer 1

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

Answer 2

Answer:

y=2x

Step-by-step explanation:

y is the amount of money made from the sold books

x is the number of books that are sold

since every book is sold for 2 dollars it's 2x,

so that mean x is multiplied by 2 to get y
