Question

Rani bought one and a half dozens of hair pin for 45. How much did each hair pin cost her? ​

Answer 1

each hair pin costs 2.5

Explanation:

one dozen = 12

half dozen = 6

one and a half dozen = 12 + 6 = 18

given the cost of one and a half dozen is 45

then divide this cost by 18 to find the cost of each hair pin

45 ÷ 18 = 2.5
