Mai and Tyler are selling items to earn money for their elementary school. The school earns w dollars for every wreath sold and p dollars for every potted plant sold. Mai sells 14 wreaths and 3 potted plants and the school earns $70.50. Tyler sells 10 wreaths and 7 potted plants and the school earns $62.50. This situation is represented by this system of equations 14w+3p=70.50 10w+7p=62.50: Explain why it makes sense in this situation that the solution of this system is also a solution to 4w+(-4p)=8.00.
