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
__ month(s) at a time
To find out which option is less expensive, we need to compare the total cost for ordering contact lenses for a year.
If we pay for 12 months at one time, the cost would be $300.
If we pay for 1 month at a time, the cost for each month would be $30. Therefore, the cost for 12 months would be $30 * 12 = $<<30*12=360>>360.
So, ordering contact lenses per year by paying for 1 month at a time is less expensive.
To determine which option is less expensive, we can calculate the cost for ordering contact lenses per year using both payment options.
If each month's supply costs $30, then the cost for a year would be:
12 months * $30/month = $360.
On the other hand, if a year's supply costs $300, then it is less expensive to order contact lenses by paying for 12 months at one time rather than paying for 1 month at a time.
Therefore, paying for 12 months at one time is the less expensive option.
To determine which option is less expensive, we need to calculate the total cost for each option.
Option 1: Paying for 12 months at one time
The cost for a year's supply of contact lenses is $300. Since we are paying for 12 months at once, we multiply $300 by 1 to get the total cost:
Total cost = $300 × 1 = $300
Option 2: Paying for 1 month at a time
The cost for a month's supply of contact lenses is $30. Since we are paying for each month individually, we need to calculate the total cost for 12 months:
Total cost = $30 × 12 = $360
Comparing the total costs:
- 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, as it costs $300 compared to $360 when paying for 1 month at a time.
