Currently guavas cost 30 cents/pound. Due to a disease affecting the guava trees it is expected that next month guavas will cost 50% more than they do currently. How much are guavas expected to cost next month? Choose the correct answer
A) 50 cents /pound
B) 45 cents /pound
C) 55 cents /pound
D) 60 cents /pound
E) 65 cents /pound
If a new cost is p percent greater than the old cost, then (new cost) = (old cost) + (p/100)(old cost).   In this case, (new cost) = 30 cents/pound + (50/100)(30 cents/pound)   = 30 cents/pound + 15 cents/pound   = 45 cents /pound   Answer : 45 cents /pound
