Answer 1

To determine which option is less expensive, we need to compare the total cost of ordering 12 months at one time versus paying for 1 month at a time.

1. Cost of ordering for a year (12 months) at one time:

   • Cost = $300

2. Cost of ordering for 1 month at a time:

   • Cost for 1 month = $30
   • Total cost for 12 months = 12 months × $30/month = $360

Now we can compare the two costs:

• Cost for a yearly supply (ordering 12 months at once): $300
• Cost for 1 month at a time for 12 months: $360

Conclusion: Ordering 12 months at a time ($300) is less expensive than paying for 1 month at a time ($360).
