Can someone explain the best way to approach this problem?
It takes machine A x hours to manufacture a deck of cards that machine B can manufacture in 1/x hours. If machine A operates alone for y hours and is then joined by machine B until 100 decks are finished, for how long will the two machines operate simultaneously?
a) (100y-x)/x^2 +1
b) (100x-y)/x^2 + 1
c) (100y-x^3-x)/x^2 + 1
d) (100y-x^2y-y)/x^2 +1
e) 100x/x^2+1
