Cindy deposited $350 into a savings account. As long as the account balance remains at or above $200, she does not have to pay a service fee for the account. For how long can she withdraw $30 a month without having to pay service fees? A) 5 months B) 6 months C) 7 months D) 8 months E) 9 months

5 months

Step-by-step explanation:

Cindy deposited $350 into a savings account

The acct balance remains above $200

We are required to find the number of months that it will take to $30 a month

Let y represent the number of months

y × 30 < 350-200

30y < 150

Divide both sides by the coefficient of y which is 30

30y/30 < 150/30

y < 5

Hence the number of months required is 5 months

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
