Answer: It costs $1.22 to make each paperweight.
Step-by-step explanation:
Given : Selling price of 95 identical paperweights = $230.85
Then, Selling price of 1 paperweight = (Selling price of 95 identical paperweights) ÷ 95
= $ (230.85 ÷ 95) = $ 2.43
Now, selling price of each paperweight = 2 x ( cost of each paperweight)
⇒ cost of each paperweight = (selling price of each paperweight ) ÷ 2
⇒ cost of each paperweight = $ 2.43 ÷ 2 = $ 1.215 ≈ $ 1.22
Hence, it costs $1.22 to make each paperweight.
