Answer:
£300
Step-by-step explanation:
We apply the formula for Simple Interest:
where P = Principal
R = Rate of interest
T = Time elapsed (in years)
We are given that P = £5000, R = 3%, T = 2 years
The interest after 2 years will be:
I = £300
The interest Becky will get after 2 years will be £300.
