Week 439 (17th April 2026) 

Lizzie was gifted some money by a relative for her 18th birthday. 

She invested the money in a savings account that pays 4% simple interest per year.    

After 5 years the total interest that Lizzie’s investment had earned was £360.    

Find the total value of Lizzie’s investment after 5 years.   

Answer:   

First divide 360 by the percentage multiplier of 0.04 to get £9000   

Then divide that by 5 as it has been 5 years to get £1800   

Therefore, the total value of the investment is 1800 + 360 = £2160
