When Dea breaks open her piggy bank she finds a total amount of $15 she spends $0.5 every month on a snow cone write an equation for the given solution use y=Mx+b

The equation is .

Step-by-step explanation:

Given:

Total amount in the piggy bank = $15

Amount spent each month on snow cone = $0.5

We need to write the equation modelling this situation.

Solution:

Let 'x' be denoted as number of months.

Let 'y' be denoted as Amount left with him.

So we can say that;

Amount left with him is equal to Total amount in the piggy bank minus Amount spent each month on snow cone multiplies by number of months.

framing in equation form we get;

using we can say that;

Hence the equation is .
