The Answer of If $P is invested in a bank account earning r% interest a year, compounded continuously, the balance, $B, at the end of t years is given by $B = f ( P , r , t ) = P e ^ { r t / 100 }$ (a)What are the units of $\partial B / \partial t$ ?
(b)What is the practical interpretation (in terms of money)of $\partial B / \partial t$ ?

If $P Is Invested in a Bank Account Earning R B=f(P,r,t)=Pert/100B = f ( P , r , t ) = P e ^ { r t / 100 }B=f(P,r,t)=Pert/100

If $P Is Invested in a Bank Account Earning R $B = f ( P , r , t ) = P e ^ { r t / 100 }$
