Suppose contact lenses cost $300 for a year’s supply or $30 for a month’s supply. Which is less expensive to order per year, paying for 12 months at one time or paying for 1 month at a time?(1 point)

Answer 1

To determine which option is less expensive per year, we need to compare the total cost of each option.

For 12 months at one time:
Cost per year = $300

For 1 month at a time:
Cost per month = $30
Cost per year = $30 x 12 = $360

Therefore, paying for 12 months at one time is less expensive per year as it costs $300, whereas paying for 1 month at a time would cost $360.
