Alice's Laptop Budget Inequality

Alice is interested in buying a new laptop. She finds a laptop that costs $800 at one store and another that costs $600 at a different store. After comparing the prices, she discovers that the second store offers a 10% discount on their laptop. Alice can represent the total cost $C$ of the laptop at the second store with the inequality:

$C = 600 - 0.10(600)$.

If Alice has a budget of $700, which of the following inequalities accurately represents her budget constraint based on this comparison?
