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
answer to this question
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
new question Is it possible that Santiago bought 10 board books and 5 softcover books? Use your equation from part A to check. Explain your answer.
To check if it is possible for Santiago to have bought 10 board books and 5 softcover books, we can substitute these values into the equation and see if it holds true.
1.5(10) + 0.5(5) = 15 + 2.5 = 17.5
The total cost is calculated as 17.5, which is not equal to 20. Therefore, it is not possible for Santiago to have bought 10 board books and 5 softcover books.
