So, i am pretty new at a subject called "applied mathematics in economics" so take me easy : d

i have this problem:

to provide for future education costs a family considers various methods of saving. assuming that the saving lasts 10 years at an interest rate of 7,5%/year
a) calculate the value of the fund after 10 years when a single deposit of 2000£ is made annualy
b) how much should be deposited each year if the final value is 4£
c) how much should be deposited each month if the final value is 4£

the only formula i know is sn = s₀*(1+i)ⁿ but i don't think that this is applicable here?

in advance and i am really sorry if it's very easy but i just don't understand

29 is the correct answer

step-by-step explanation:

1. 3

2. 4

3. 1

hope this ! have a great day.

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc
