Suppose contact lenses cost $300 for a year’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?
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.
If each year's supply costs $300, then paying for 12 months at one time would be:
$300
Paying for 1 month at a time would be:
$300 / 12 = $25 per month
Therefore, paying for 1 month at a time would be less expensive, as it would cost $25 per month compared to the total cost of $300 for 12 months.
To determine which option is less expensive, let's calculate the total cost for each option:
Option 1: Paying for 12 months at one time
Total cost for 12 months = $300
Option 2: Paying for 1 month at a time
Total cost for 1 month = $300 / 12 = $25
Since you'll be paying $25 per month for 12 months, the total cost for paying monthly would be:
Total cost for 12 months = 12 * $25 = $300
Both options have the same total cost of $300 for a year's supply of contact lenses. Therefore, there is no difference in cost between paying for 12 months at one time or paying for 1 month at a time.
To determine which option is less expensive, let's compare the total costs for paying for 12 months at once and paying for 1 month at a time.
First, let's calculate the cost of paying for 12 months at one time. Since the cost for a year's supply of contact lenses is $300, paying for 12 months at once would simply be $300.
Now let's calculate the cost of paying for 1 month at a time. Since there are 12 months in a year, we need to multiply the cost of one month by 12. Dividing $300 by 12 would give us $25 per month.
Therefore, the total cost for paying for 1 month at a time for a year would be $25 x 12 = $300.
As you can see, both options have the exact same total cost of $300 per year. So, whether you pay for 12 months at one time or pay for 1 month at a time, the expense would be the same.
