Practice for the Lookups unit. Rentals list the bike ID; the Fleet tab has each bike's type and hourly rate. Pick VLOOKUP, XLOOKUP or INDEX with MATCH as you like: the checker looks at results, not at which function you chose, unless the task names one.
Remember to lock the Fleet ranges with $ before you fill a lookup down, to use an exact match, and to decide what a missing bike should show.
