Answer:

Your answer is 10

Step-by-step explanation:

So if you have to pay 55 out front and then continue to pay 19.50 monthly the equation will look like this:

19.50*m + 55 = x

(M stands for month)

She has 250 dollars to spend so add that in for x

19.50*m + 55 = 250.  

Use inverse operations.

250-55 and 55-55

19.50*m = 195

195/19.50 and 19.50/19,50

m=10

Your answer is 10
