Colleen has $400 in a savings account that earns 10 % interest per year. The interest 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. $_____

Identify Amount, Rate, Time: Step 1: Identify the principal amount, interest rate, and time. Principal (p) = $400, Interest rate (r) = 10%, Time (t) = 1 year. Convert the interest rate to a decimal: r = 10% = 0.10.Use Formula to Calculate: Step 2: Use the formula i = prt to calculate the interest. Interest (i) = 400 * 0.10 * 1.Perform Multiplication: Step 3: Perform the multiplication to find the interest. i = 400 * 0.10 * 1 = $40.

Identify Amount, Rate, Time: Step $1$ : Identify the principal amount, interest rate, and time. $\newline$ Principal $p$ = $\$400$ , Interest rate $r$ = $10\%$ , Time $t$ = $1$ year. $\newline$ Convert the interest rate to a decimal: $r = 10\% = 0.10$ .
Use Formula to Calculate: Step $2$ : Use the formula $i = prt$ to calculate the interest. $\newline$ Interest ( $i$ ) = $400 \times 0.10 \times 1$ .
Perform Multiplication: Step $3$ : Perform the multiplication to find the interest. i = $400 \times $0$ . $10$ \times $1$ = \$(\(40$)\.
