Question

2. If A= p + prt, which of the followingexpressions represents t?A-b.A+PPYC.рprd.Y

Answer 1

We have this expression:

`A=p+\text{prt}`

We need to do the following steps to solve the equation for t:

`A=p(1+rt)\Rightarrow(A)/(p)=1+rt\Rightarrow(A)/(p)-1=rt\Rightarrow((A)/(p)-1)/(r)=t_{}`

Then, t is the same as:

`t=((A)/(p)-1)/(r)=((A-p)/(p))/(r)=(A-p)/(pr)`

Then, the answer is (A - p)/pr.
