Hi, can you please help calculate the spending multiplier for the following hypothesis case I created?

Would you mind if you explain the steps you may take?

The Addis Ababa Research calculated that students who attend Addis Ababa University spend about 5,520 Birr (Ethiopian currency) each in the local economy for a total of 50.45 million Birr (Ethiopian currency). In total, the impact of their spending on the local economy is 63 million Birr (Ethiopian currency). Calculate the size of the student spending multiplier.

Best regards
