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 many more must it snow before school is cancelled? its an algebraic inequality so what is the problem for it

Okay so we know that it has to reach at least 10 inches for the school to announce.

We know it has already snowed 1.5 inches.

We want to know how much more it needs to snow to reach 10 inches in order for there to be an announcement.

You can form an equation like this:

1.5+ x= 10
Subtract 1.5 from each side.

X= 8.5

So now we know that we need 8.5 inches more in order for it to reach 10 inches and for there to be an announcement.

Num of plants = (original#ofplants)*(1.6)^t
