Answer 8

Let x be the weekly salary prior to the increases.
The total amount of the increases is 0.043x + 0.0325 = 0.0755x
Therefore the new weekly salary is given by:
x + 0.0755x = 688.32 ............. (1)
Now you just need to solve equation (1) to find the value of x, the weekly salary prior to the increases.
