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?
To determine which method is less expensive, we need to compare the total cost of ordering 12 months at one time versus ordering 1 month at a time.
If the lenses cost $30 for a month's supply, then the cost for 12 months at one time would be 12*30 = $<<12*30=360>>360.
Comparatively, if the lenses cost $300 for a year's supply, then ordering 12 months at one time would cost $300.
Therefore, ordering 12 months at one time is less expensive as it costs $300 compared to $360 for ordering 1 month at a time.
To determine which option is less expensive per year, we need to compare the total cost of each option.
Option 1: Paying for 12 months at one time
The cost of a year's supply is $300.
Option 2: Paying for 1 month at a time
The cost of a month's supply is $30.
Since there are 12 months in a year, the cost of ordering 12 times would be: 12 x $30 = $360.
Therefore, paying for 12 months at one time is less expensive as it costs $300, compared to paying for 1 month at a time, which costs $360.
To determine which option is less expensive, let's calculate the total cost for each scenario.
Option 1: Paying for 12 months at one time
If the cost for a month's supply is $30, then the cost for 12 months would be 12 * $30 = $360.
Option 2: Paying for 1 month at a time
The cost for a year's supply is $300, so paying for 1 month at a time would cost $300 for the whole year.
Based on the calculations, paying for 1 month at a time is less expensive in this case, with a total cost of $300 compared to $360 when paying for 12 months at one time.
Therefore, it is recommended to pay for 1 month at a time to save money.
