Question

Carla is a US student. She is purchasing used textbooks, because she is balling on a budget (pro tip: don't ever buy new books)! She purchased a math book and a reading book, and the total was $54. The price of the math book is $8 more than 3 times the cost of the reading book. What is the cost of each book?

Answer 1

I think this is how you do it. Use x as the price of the reading book, then make it an equation. Let me know if you don’t understand any of the steps. Hope that helps!
