Carissa bought a box of candy to share with her friends. However, when she opened the box there was much less candy than she expected. The box says it contains a total of \(420\) grams of candy. In the box, there are two types of candies: Sour Sassies and Caramellos. Each Sour Sassy has a mass of \(15\) grams and each Caramello has a mass of \(10\) grams.
If she counts \(10\) Sour Sassies and \(25\) Caramellos in the box, was the information on the box correct? Justify your answer.
