Margo has $100 in her bank account and is saving $50 per month. Jon has $75 in his bank account and is saving $100 per month. Which of the following systems of equations would tell how many months, x, it will take for Margo and Jon to have the same amount of money, y? y=100 + 75% y = 75+. 752 y=100 + 503 y = 75+. 1000 y = 75 + 50.2 y = 75+752 y=100 + 50% y = 75+.50.2​
