• the 220 - count offer is a better buy because it has the lower unit price.
• the 150 - count offer is a better buy because the cost per pen is less than the cost per pen with the 220 - count offer.

Explanation:

Step1: Calculate unit price for 150 pens

Unit price = Total price / Number of pens. For 150 pens at $17.49, unit price is $\frac{17.49}{150} \approx 0.1166$ dollars per pen.

Step2: Calculate unit price for 220 pens

For 220 pens at $39.99, unit price is $\frac{39.99}{220} \approx 0.1818$ dollars per pen.

Step3: Compare unit prices

Since $0.1166 < 0.1818$, the 150 - pen offer has a lower unit price, so it's a better buy.

Answer:

The 150 - count offer is a better buy because it has the lower unit price. (Corresponding option: The 150 - count offer is a better buy because it has the lower unit price.)
