-------------------------------------
Define x :
-------------------------------------
Let x be the number of weeks needed.

-------------------------------------
Navor :
-------------------------------------
Navor has $800 and is spending $30 per week:
800 - 30x

-------------------------------------
Rashid :
-------------------------------------
Rashid has $150 and is saving $20 per week:
150 + 20x

Solve x:
-------------------------------------
800 - 30x = 150 + 20x
50x = 800 - 150
50x = 650
x = 13
