Answer:

y = -3.5x + 230

Step-by-step explanation:

Find how much money she has now:

200 + 30 = $230

To create an equation to find how much money she has left, let y represent the amount of money left, and x represent the number of days.

Coffee will cost $3.50 every day, so 3.5x will represent all of the money that she will spend on coffee.

The amount of money she has left will be represented by 230 - 3.5x.

Rearrange this to put x in front, and let this equal to y to create the equation:

y = -3.5x + 230

So, the equation that can be used to find how much money she has left is y = -3.5x + 230
