Movietime!

by zagcollins » Mon Jul 28, 2008 9:08 am
A certain movie depicted product A in 21 scenes, B in 7 scenes, C in 4 scenes, and D in 3 scenes.The four product manufacturers paid amounts proportional to the number of scenes in which their product was depicted in the movie. If each manufacturer paid x dollars per scene, how much did the manufacturer of product D pay for this advertising?

1) Manufacturers of products A and B together paid a total of $560,000 for this advertising.
2) The manufacturer of product B paid $60,000 more for this advertising than the manufacturer of product C paid.

It's C

From (1) you have $560000 / (21 + 7) = X (the ammount paid by scene)
then multiply X * 3 and you have the ammount D paid for the advertisement

From (2) you have $60000 / (7 - 4) = X
And again multiply by 3.

I guess u meant 'D' :lol:
D- Either statement by itself is sufficient to answer the
question..

C- both statements together are needed to answer the
question, but neither statement alone is sufficient
