Answer 2

The amount of snowfall in March would be 2.4f.

Step-by-step explanation:

Since we have given that

Let 'f' be the amount of snowfall in February.

If there is 40% more snowfall than in February in March,

So, the amount of snowfall would be

$f+\dfrac{100+40}{100}f\\\\=f+\dfrac{140}{100}f\\\\=f+1.4f\\\\=2.4f$

Hence, the amount of snowfall in March would be 2.4f.
