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)
To determine which option is less expensive per year, we can compare the total costs for both options.
Option 1: Paying for 12 months at one time
Cost per year = $300
Option 2: Paying for 1 month at a time
Cost per month = $30
Total cost for 12 months = 12 * $30 = $360
Comparing the two options, it is less expensive to order the lenses by paying for 12 months at one time, as it costs $300 per year, while paying for 1 month at a time costs $360 per year.
To determine which option is less expensive per year, we need to compare the cost of ordering contact lenses for 12 months at one time and the cost of ordering contact lenses for 1 month at a time.
By paying for 12 months at one time, the cost would be $300.
By paying for 1 month at a time, we need to calculate the cost for 12 months. Since the cost for 1 month is $30, the cost for 12 months would be $30 multiplied by 12, which equals $360.
Therefore, paying for 12 months at one time is less expensive, as it costs $300 compared to $360 for 1 month at a time.
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.
