The school will not announce a snow day unless there is at least 10 inches of snow on the ground. If it has already snowed 1.5 inches, how much more must it snow before school is cancelled?

Respuesta :

It must snow 8.5 inches before school is cancelled.

Given,

Least level required for snow day = 10 inches

It has already snowed = 1.5 inches

Let,

x be the snow required more for the school to announce snow day.

x = Level of snow required - Already snowed

[tex]x= 10-1.5\\x=8.5\\[/tex]

It must snow 8.5 inches before school is cancelled.
