You would take the amount of increase and divide it by the amount of total cost over the time period of certain months. Then you would multiply that number by the percentage of increase gained, and subtract 96.12 to get your answer.
Umm, I think it is the first one.
The addictive inverse is positive while the multiplicative inverse is negative

Answer:
Add 30 to each side so L+L/3+L=630 then Multiply each side by 3 so 3L+L+3L=630 then add together the L's to get 7L=630 then divide by 7 so L=90
