Final answer:
To find the amount of money that Isobel must pay back after 3 years with compound interest on a loan of £80,000, use the formula: Principal Amount x (1 + Interest Rate)^Number of years.
Step-by-step explanation:
To find the amount of money that Isobel must pay back after 3 years with compound interest, we can use the formula:
Principal Amount x (1 + Interest Rate)^Number of years
Plugging in the values given in the question, we have:
£80,000 x (1 + 0.06)^3
Calculating this expression will give us the total amount that Isobel must pay back.
