Question 1013332
Marge has $30 and is saving at the rate of $7 per week. 
M(x) = 30 + 7x
-----------------------

Hank has $90 and is saving a the rate of $3 per week. 
H(x) = 90 + 3x
------------------------

How many weeks will it take for them to save the same amount? 
---------
Solve:: M(x) = H(x) for "x"::
------
30+7x = 90+3x
4x = 60
x = 15 weeks
