Final answer:
Kim will save $678 in one year by using a home manicure kit instead of going to a salon every two weeks. The calculation takes into account the annual cost of salon visits and the one-time purchase of a manicure kit and nail polish for the year. However, the correct answer according to the calculation is not provided in the options.
Step-by-step explanation:
To calculate how much Kim will save in one year, we first determine the total cost of salon manicures and pedicures for a year. Since she goes every two weeks, there are 52 weeks in a year, which results in 26 visits to the salon. The cost of one salon visit for a manicure and pedicure is $28, so the total cost for the year would be 26 visits × $28 per visit = $728.
Kim's alternative is to use a home manicure kit and her own nail polish. The initial cost of the home manicure kit is $30, plus $20 for the nail polish for the year, leading to a total cost of $30 + $20 = $50.
Therefore, the savings for the year when using the home kit compared to the salon visits is $728 (salon cost) - $50 (home kit cost) = $678 savings.
The correct answer is: a. $184 b. $144 c. $104 d. $64
This calculation shows that the correct choice is not listed, as the actual saving is much higher according to these calculations.
