=VLOOKUP($A6,RentalRates,2,0) is the lookup for this.
<u>Explanation:</u>
Utilize the LOOKUP capacity to look into an incentive in a one-section or one-push go, and recover an incentive from a similar situation in another segment or one-push go. The query work has two structures, vector and cluster. This article depicts the vector structure.
In computer science, a lookup table is a cluster that replaces run time calculation with a more straightforward exhibit ordering activity. The investment funds as far as handling time can be critical, since recovering an incentive from memory is regularly quicker than experiencing a "costly" calculation or information/yield activity.
