Estou com dúvida em um problema

Main post link -> https://brilliant.org/assessment/d/algebra-and-number-theory/2/

Um dos problemas de Teoria don Numeros e Algebra do nivel 2, esta me deixando muito confuso, a única resposta que eu consigo chegar é 245 centavos, qualquer outro resultado me parece estranho, será que alguem poderia me ajudar, desde ja agradeço.

segue pergunta: "A taxa de pedágio na rodovia I-94 é de 7 centavos para cada quilômetro percorrido. Se o Calvin dirigir 35 quilômetros na rodovia, quanto ele pagará de pedágio, em centavos?"

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.
