Answer:
You should deposit 700 pieces today if you want to use the total amount to pay the fees.
Step-by-step explanation:
Suppose, you should deposit [tex]P[/tex] number of pieces today.
Formula for simple interest: [tex]I= P*r*t[/tex] , where I = Amount of interest, P= Initial deposit amount, r= rate of interest in decimal form and t= time duration.
Here, the [tex]P[/tex] number of pieces is deposited at an annual interest rate of 10% for three years. That means, [tex]r= 10\%= 0.10[/tex] and [tex]t= 3[/tex]
Using the above formula, we will get.......
[tex]I= P*0.10*3 = 0.3P[/tex]
Given that, you need total 910 pieces of muggle-money to study after three years. So, the equation will be......
[tex]P+I= 910\\ \\ P+0.3P=910\\ \\ 1.3P=910\\ \\ P=\frac{910}{1.3}=700[/tex]
So, you should deposit 700 pieces today if you want to use the total amount to pay the fees.
