Final answer:
Tenille will have $3,000 after 10 years with a simple interest rate of 5%.
Step-by-step explanation:
To calculate the amount Tenille will have after 10 years with a simple interest rate of 5%, we use the formula:
Final Amount = Principal + (Principal x Interest Rate x Time)
Given that Tenille made $2,000 and she lets it earn interest for 10 years, we can substitute the values into the formula:
Final Amount = $2,000 + ($2,000 x 0.05 x 10)
Simplifying the equation gives:
Final Amount = $2,000 + $1,000
Final Amount = $3,000
Therefore, after 10 years, Tenille will have $3,000.
