Q. Darnel has $50 in a savings account that earns 5% annually. The interest is not compounded. How much interest will he earn in 5 years? Use the formula i=prt, where i is the interest earned, p is the principal (starting amount), r is the interest rate expressed as a decimal, and t is the time in years.$_____
Principal Amount: Darnel's principal amount p is $50.
Annual Interest Rate: The annual interest rate r is 5%, which as a decimal is 0.05.
Time: The time t is 5 years.
Calculate Interest: Now we use the formula i=prt to calculate the interest. So, i=$(50)∗0.05∗5.
Multiplication: Doing the multiplication, i=$2.5×5.
