Answer:
total strength of the student = 1.24876
Step-by-step explanation:
individual spend by student is 2,760 pound
total spending = 50.45 million
therefore total student strength is
![(50,450,000)/(2,760) = 18,279](https://img.qammunity.org/2020/formulas/business/high-school/ssukm2qvlhhucjzabwq3phvdol0dftq1lh.png)
here this total strength f student act as multiplier.To get total impact multiplier which is constant value is multiplied by total spending..
in the question, total Impact is greater than total spending. Thus:
![\textup{Total spendings}* \textup{Multiplier} =\textup{Total impact on the economy}](https://img.qammunity.org/2020/formulas/business/high-school/utlnxpetvdcl3kdu1ap6e9kzd7w4owwj2d.png)
![$50.45* {Multiplier} =$63million](https://img.qammunity.org/2020/formulas/business/high-school/v32grzid94nkks259c2z1ysphliqhukqma.png)
![Multiplier =(63)/(50.45) = 1.24876](https://img.qammunity.org/2020/formulas/business/high-school/5ilws5i3l2djslkxwli3bmlxzj3no4rhvs.png)
total strength of the student = 1.24876
