To calculate the total amount Josh will have in his savings account after 3 years with simple interest, we can use the formula:
\[ i = prt \]
Where:
- \( p \) = Principal (starting amount) = $40,000
- \( r \) = Interest rate (as a decimal) = 14.43/100 = 0.1443
- \( t \) = Time in years = 3
Now, let's calculate the interest earned (\( i \)):
\[ i = 40,000 \times 0.1443 \times 3 \]
Calculating this step-by-step:
-
Calculate \( 40,000 \times 0.1443 \): \[ 40,000 \times 0.1443 = 5,772 \]
-
Now, multiply that result by 3: \[ 5,772 \times 3 = 17,316 \]
So, the interest earned over 3 years is \( i = 17,316 \).
To find the total amount in the account after 3 years, we add the interest earned to the principal:
\[ \text{Total amount} = p + i = 40,000 + 17,316 = 57,316 \]
Therefore, in 3 years, Josh will have a total of $57,316 in his savings account.
