Answer:
I don't see any options for inequalities, so I wrote one based on the information.
Explanation:
We'll assume that the drinks and cake ($17) are the only items Mr. Saslow needs to purchase and that the remainder may be used on whatever extras he wants. In this case, candy.
He starts with $32 and spends $17. The remainder may be spent on candy (all or none). This can be expressed as an inequality. Let C be the cost of the candy.
C
($32 - $17)
C
($32 - $17)
C
($15)
