Q. Lily has $30 in a savings account. The interest rate is 10% per year and is not compounded. How much interest will she earn in 1 year? Use the formula i=prt, where i is the interest earned, p is the principal (starting amount), r is the interest rate expressed as a decimal, and t is the time in years.$___
Convert to Decimal: Step 1: Convert the interest rate from a percentage to a decimal.To convert 10% to a decimal, divide by 100.Calculation: 10÷100=0.1
Calculate Interest: Step 2: Use the formula i=prt to calculate the interest.Substitute p=$30, r=0.1, and t=1 year into the formula.Calculation: i=30×0.1×1
Find Total Interest: Step 3: Perform the multiplication to find the interest.Calculation: 30×0.1×1=3
