1. Determine the savings at the end of January and the end of February

Savings at the end of January = Savings at the start of February = $\char36{}300$
Savings at the end of February = Savings at the start of March = $\char36{}1300$

2. Calculate the percentage increase

Increase = $1300 - 300 = \char36{}1000$
Percentage increase = $\frac{1000}{300} \times 100\% = \frac{1000}{3}\% = 333\frac{1}{3}\%$

Answer

$233\frac{1}{3}\%$
