Santiago is working at his mom’s daycare this summer. His mom has asked him to check out the library book sale to look for books they might be able to use in the daycare. When he gets to the book sale, he sees that board books are $1.50 and soft cover books are $0.50. He picks out a variety of books and spends $20
Write a two-variable equation to represent this situation. Be sure to define the variables you use in your equation
Let's define:
x = number of board books
y = number of soft cover books
Since board books are $1.50 each and soft cover books are $0.50 each, the equation representing the total cost of the books Santiago bought is:
1.5x + 0.5y = 20
