S=C(1+R/100)^5

Postby mcpeakmelissa on Fri Sep 17, 2010 3:15 am

If the inflation rate in Italy is 1.80%, the item is expresso at 2.35 euros what would it be in 5 years?
The equation: S=C(1+R/100)^5

So it is: S=2.35(1+1.8/100)^5

Not sure how to calculate? Need to show my work so if you could help that would be wonderful.

I get to this part:

S=2.35(1+1.8/100)^5
S=2.35( ? )

Now do the indicated calculations. A calculator will be useful. :wink:

So I do what is in the parenthesis first which comes out to .0286 now mutiply this by 5 and the answer is 0.14. Is this correct? :confused:

So I recalculated with calculator and came up with 355.0488005, but we move 3 decimal points and get the increase after five years as .355 or rounded .36.
Is this correct?

How did you get that 1 + 0.018 equalled 0.0286?

I see a power of 5, but not a multiplier. Where is your 5 coming from?

What happened to multiplying by 2.35? :confused:
