First of all, observe that all fractions exist as long as b is not zero.
Multiply both numerator and denominator of the first fraction by 3:

Now all fractions have the same denominator. Under the assumption that b is not zero, multiply both sides by 3b:

Subtract 3b from both sides:

Subtract 2 from both sides:

Divide both sides by 2:

To find it it is
ax^2+bx+c
if the first term (a) is 1 then c=b/2
b=-1/4
(-1/4)/2=-1/4 times 1/2=-1/8
k=-1/8
429 ÷ 39= 11
11 ÷ 2= 5.5 (5 1/2)
It takes 5 1/2 weeks to produce 429 wetsuits
