If 5 pens cost $8, how much would 12 pens cost?

Answer

To determine the cost of 12 pens given that 5 pens cost $8, we start by finding the cost per pen. 1. **Calculate the cost per pen**: - If 5 pens cost $8, then the cost per pen is: Cost per pen = Total cost / Number of pens = $8 / 5 pens = $1.60 per pen. 2. **Calculate the cost for 12 pens**: - Now that we know each pen costs $1.60, we can find the total cost for 12 pens by multiplying the cost per pen by the number of pens: Total cost for 12 pens = Cost per pen × Number of pens = $1.60 × 12 = $19.20. Therefore, the cost for 12 pens would be $19.20.
