You want to study at the Hogwarts School of Witchcraft and Wizardry after three years. You need 910910 pieces of muggle-money to
Sonja [21]

Answer:

<em>You should deposit 700 pieces today if you want to use the total amount to pay the fees.</em>

Step-by-step explanation:

Suppose, you should deposit P number of pieces today.

<u>Formula for simple interest</u>:    I= P*r*t , where I = Amount of interest, P= Initial deposit amount, r= rate of interest in decimal form and t= time duration.

Here, the P number of pieces is deposited at an annual interest rate of  10% for three years. That means,  r= 10\%= 0.10 and t= 3

Using the above formula, we will get.......

I= P*0.10*3 = 0.3P

Given that, <u>you need total 910 pieces </u>of muggle-money to study after three years. So, the equation will be......

P+I= 910\\ \\ P+0.3P=910\\ \\ 1.3P=910\\ \\ P=\frac{910}{1.3}=700

So, you should deposit 700 pieces today if you want to use the total amount to pay the fees.

jonny [76]
