you deposit 300 in an account that pays 5 1/2% annual interest compounded cnyinuously find the balance at the end of 5 years

algol [13]

First find the multiplier: 5.5% + 1 = 1.0505.

Then we do amount x (multiplier) to the power of how many years.

300 x (1.0505)^5

The answer is 383.79696707.

We round this to 2dp, making it £393.80

REMEMBER UNITS!!!

Hope this helps xox :)
