Yasemin deposited \[\$1000\] into a savings account. The relationship between the time, \[t\], in years, since the account was first opened, and Yasemin's account balance, \[B(t)\], in dollars, is modeled by the following function. \[B(t)=1000 \cdot e^{0.03t}\] How many years will it take for Yasemin's account balance to reach \[\$1500\]?
