Final answer:
Upon calculation of the price per year for each store, Store 1 offers the best price at $5.40 per year, followed by Store 3 at $6.75 per year after applying a 10% discount, and finally Store 2 at $9.00 per year.
Step-by-step explanation:
To determine which store offers the best price, let's compare the costs in terms of dollars spent per year for each option. Assuming there are no additional hidden costs or fees, we can calculate the price per year by dividing the total cost by the number of years.
- Store 1: $27 for 5 years = $27/5 years = $5.40 per year
- Store 2: $27 for 3 years = $27/3 years = $9.00 per year
- Store 3: $30 with a 10% discount for 4 years. First, calculate the discount: 10% of $30 is $3, so the actual cost is $30 - $3 = $27 for 4 years. Now, divide by the number of years: $27/4 years = $6.75 per year.
Comparing the prices per year, Store 1 offers the lowest price at $5.40 per year.
