The equation is x(5(2))=s or x(10)=s when x = number of weeks
Step-by-step explanation:
For 6 weeks, all you have to do is plug in the 6 where the <em>x</em> is.

6(10) = s
60 = s
or

Multiply -9 and 5j first to get -45j
Multiply -9 and k to get -9k
Let's put it into perspective.
x/(x+5)
If increase by 3:
(x+3)/(x+8) = 3/4
Cross multiply.
4(x+3)=3(x+8)
4x+12 =3x+24
Solve algebraically.
4x-3x = 24-12
x = 12
Therefore, original fraction is:
12/17
