Question

Marli has $1200 in her savings account. She wants at least y in her account at the end of the year.she withdraws $150 each month.which inequality represents this situation, where x is the number of months?

Answer 1

Y = 1200 - 150x

You can really do this one easily yourself. Put yourself into the shoe of Marly, so yes first you know that you have $1200 in your account, then you know that each month (number of month being x) you withdraw $150 (so 150 times x), as you withdraw it you take it out from your $1200, and the total is what you have left (y)
