105*2000= 210000

Area of each circle,   r= 17.5 cm
Area = pi*(17.5)^2 = 962.1127

Number of circles = 210000/962.1127 =218circles  

OR 
105/35 = 3 circles in a column
2000/35 = 57

57*3 = 171 

A roll of the material costs ₦3,000 and other costs involved in making the caps are as follows:
thread and stiffening ₦3 per cap, labour ₦4 per cap and other costs ₦10 per cap

218 circles 
material  cost per cap = 3000/218= 13.76 N
thread and stiffening cost per cap = 3 N
Labor = 4N
 other costs per cap=  10 N

Add them up to get the cost per cap

The cost price per cap, considering material and additional costs, is approximately ₦30.76.
