You can put this solution on YOUR website! ewhen a real-life quantity increases by a fixed percent each year (or other time period), the amount y of the quanitity after t years can be modeled by the equation: P = a(1+r)^t
1. P= 1300(1 + .07)^t
2. P= 1300(1.07)^12 add the quantity first
P= 1300(2.252) muiltiply by exponent
p=2927.85
