Differential Equation - how to solve a simple equation..

Hi,

I am really struggling to solve this differential using the basic rules that I know.

**There should be a dot above the A in the numerator on the left hand side** **and brackets around the fraction on the right hand side ** but I wasn't sure how to do that.

Any help gratefully received!!

Imagine a country that is adopting foreign technology *T as shown in the following equation where **A denotes the level of domestic technology and the dot over **A denotes its derivative with respect to time: *

$\displaystyle \frac{A}{A}= \phi(E)\frac{T(t)- A(t)}{A(t)}$

a) Assume that the level of foreign technology is constant and solve the differential equation above

b) What is the effect of an increase in the level of education *E? *

c) What is the effect of an increase in the rate of growth of foreign technology λ?
