Hi Kayleigh,

You would need to use the compound interest formula here, which is 
Final amount = initial amount x interest rate^years. 

-- The initial and final amounts are both in pounds
-- The interest rate is a percentage change displayed as a decimal (ie. a multiplier). For instance, if there was a 7% increase, it would be x1.07 because the next amount is the original amount (the '1') plus the added 7% (the extra '0.07').
--The number of years is added as a power to the percentage change multiplier. It shows how many times the interest has been calculated and added, because each year there is a larger amount in the bank, so you get more interest as well!  

So, for this example, you would do:
Final amount = £2000 x 1.03^5
Final amount = £2000 x 1.15927.... (leave it in the calculator)
Final amount = £2318.548.... which rounds to £2318.55

Please message me for any clarification :)
Hope that helps! :)
