This question has confused my entire family, and they all think that we need more information, and it isn’t possible. I need help to know if it really isn’t possible or none of us are understanding correctly. (For context, I’m a math one student in eighth grade, and we’re reviewing equations and inequalities.)
Here’s the question;

The original price of Doritos is the same at both Wal-Mart and County Market. Makenzie found out that Wal-Mart had Doritos on sale at $0.590 off per bag and bought four bags. Later that day, she found out that County Market had Doritos on sale at $1 off per bag and bought six bags. If she paid the same amount at both stores, what was the original price of Doritos?
