Question 1159711

Ballpoint pens cost $1.50 a dozen for the first two hundred dozen a store buys from a wholesaler $1.25 a dozen for those bought in addition to the first two hundred dozens. If the stores buy 250 dozen pens from the wholesaler, what is the average cost of ballpoint pens per dozen? 

cost of first 200 dozens = 1.5 *200 =300

cost of next 50 dozens = 1.25 *50 = 62.50

Total cost = 300+62.50 = 412.50

Average cost of dozen = 412.50/250


= $1.65 /dozen
