Kyra has a budget of 300 dollars for her holiday spending. Kyra decides to buy shoes for her grandchildren. If each pair of shoes costs 40 dollars, and Kyra has n grandchildren, which of the following inequalities represents Kyra’s budget constraint?

A \(40n \leq 300\)

If Kyra buys n pairs of shoes at a cost of 40 dollars each, she pays 40n dollars. Since she only has 300 dollars to spend, 40n dollars must be less than or equal to 300 dollars: \(40n \leq 300\)
