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
A. Write a two-variable equation to represent this situation. Be sure to define the variables you use in your equation
Let x be the number of board books and y be the number of soft cover books Santiago buys at the book sale.
The cost of the board books is $1.50x and the cost of the soft cover books is $0.50y.
The equation representing this situation is:
1.50x + 0.50y = 20
