The audio-visual technician for a hotel ordered 4 boxes of microphone cords. There are 12 cords in each box.
If there are now a total of 108 cords at the hotel, how many boxes of cords were there before the order?
A. 3 boxes
B. 5 boxes
C. 6 boxes
D. 8 boxes
D. 8 boxes
Before the order, there were 4 boxes of microphone cords, so 4 x 12 = 48 cords in total.
If there are now a total of 108 cords at the hotel, that means there were 108 - 48 = 60 cords at the hotel before the order.
Since there are 12 cords in each box, there were 60 / 12 = 5 boxes of cords before the order.
Therefore, there were 5 boxes of cords before the order.
