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)
month(s) at a time
To determine the less expensive option, we need to calculate the total cost for each option.
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 would be $30 per month. Therefore, the cost for 12 months would be $30 x 12 = $360.
Hence, paying for 12 months at one time is less expensive as compared to paying for 1 month at a time.
To determine which option is less expensive per year, we need to compare the total cost of paying for 12 months at one time versus paying for 1 month at a time.
Paying for 12 months at one time:
The cost for a year's supply of contact lenses is $300.
Paying for 1 month at a time:
The cost for a month's supply of contact lenses is $30.
To find the total cost of paying for 1 month at a time for 12 months, we multiply the cost of 1 month ($30) by the number of months (12):
Total cost = 1 month cost × 12 months = $30 × 12 = $360.
Comparing the total cost, we can see that paying for 12 months at one time ($300) is less expensive than paying for 1 month at a time ($360) per year.
Therefore, paying for 12 months at one time is the less expensive option per year in this scenario.
To determine which option is less expensive, let's compare the total costs for ordering per year.
Paying for a year's supply at one time:
The cost is $300 for a year's supply.
Paying for 1 month at a time:
The cost for 1 month is $30.
To calculate the cost for a year, we multiply the cost per month by the number of months in a year (12):
Cost per year = $30 x 12 = $360.
Comparing the two options:
Ordering per year at one time costs $300, while ordering 1 month at a time costs $360.
Therefore, ordering a year's supply at one time is less expensive.
