CFA L2 Mock AM Economics Question

I was looking at question 14 in the mock for CFAI mock exam. I was a bit confused it looks like they are using the Offer rate instead of the spot rate when calculating the value of the Forward contract. But since its selling off AUD and converting to USD and the base currency is USD/AUD using the “Up the Bid Down the Ask” criteria we should be using the ask rate right? Or am I looking at this the wrong way?
