Answer: In March Delphine's house has 1.4*F centimeters of snow.
Step-by-step explanation:
We know that in March, the snow was 40% more than in Februray.
First we need to write 40% in decimal form, for this we divide it by 100%
40%/100% = 0.4
Now, in Februray Delphine's house has F centimeters of snow.
If F corresponds to the 100%, 0.4*F corresponds to the 40%
Now, in march we have a 140% of snow, this is:
Snow = F + 0.4*F = 1.4*F
In March Delphine's house has 1.4*F centimeters of snow.
