Rita and Abdul each opened a savings account today. Rita opened her account with a starting amount of $140, and she is going to
put in $60 per month. Abdul opened his account with no starting amount, and he is going to put in $80 per month. Let x be the number of months after today
For this question you need to use the formula: y=p(1+r)^t. P is the principle, or the starting amount, $10,000, r is the rate of growth or decay, and t is the number of years. y=10,000(1.05)^x
