Answer 1

[AI-generated answer — Bot GPT 3.5]

To determine which option is less expensive per year, we need to compare the costs of purchasing 12 months at one time versus paying for 1 month at a time.

Option 1: Paying for 12 months at one time
If the contact lenses cost $300 for a year's supply, then paying for 12 months at one time would simply be $300.

Option 2: Paying for 1 month at a time
If the contact lenses cost $30 for a month's supply, then paying for 1 month at a time would be $30 multiplied by 12 months, which is $360.

Comparing the two options, paying for 12 months at one time costs $300, whereas paying for 1 month at a time costs $360. Therefore, paying for 12 months at one time is less expensive per year.

Answer 2

[AI-generated answer — Step-by-Step Bot]

To determine which option is less expensive to order per year — paying for 12 months at one time or paying for 1 month at a time — we need to compare the total costs of both options.

Option 1: Paying for 12 Months at One Time
The cost of contact lenses for a year when paying for 12 months at one time would be $300.

Option 2: Paying for 1 Month at a Time
The cost of contact lenses for a month is $30. Since there are 12 months in a year, the cost of contact lenses for a year when paying for 1 month at a time would be $30 x 12 = $360.

Comparing the two options, we can see that paying for 12 months at one time is less expensive. The total cost would be $300, which is less than the $360 cost of paying for 1 month at a time. Therefore, it is less expensive to order contact lenses by paying for 12 months at one time.

[AI-generated answer — Explain Bot]

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

Option 1: Paying for 12 months at one time:
The cost for a year's supply is $300. Since you are paying for 12 months at once, the total cost under this option is simply $300.

Option 2: Paying for 1 month at a time:
The cost for a month's supply is $30. Since there are 12 months in a year, you would need to pay $30*12 = $360 for a year's supply if you pay for one month at a time.

Comparing the two options:
- Paying for 12 months at one time: $300
- Paying for 1 month at a time: $360

Therefore, paying for 12 months at one time is less expensive than paying for 1 month at a time in this scenario.
