Answer:
The total cost (in dollars) of p pens is C = 0.09 p
Step-by-step explanation:
The cost of each pen = 9 cents
Now, 1 cent = $0.01 cents
⇒ 9 cents = $0.09
So, the cost of 1 pen = $0.09
The number of pens purchased= p
Let the total cost of p pens = c
Also, the cost of p pens = p x ( Cost of 1 pen) = p ( $0.09) = 0.09 p
or, C = 0.09 p
Hence the total cost (in dollars) of p pens is C = 0.09 p.
