Final answer:
Vince will pay back $927 to fully repay the loan.
Step-by-step explanation:
The given question involves calculating simple interest. Simple interest is calculated using the formula I = PRT, where I is the interest, P is the principal (initial amount borrowed), R is the interest rate, and T is the time in years.
In this case, Vince borrows $900 at an interest rate of 1.5% for 2 years. To calculate the amount he will pay back, we need to use the formula: I = PRT. Plugging in the values, we have:
I = 900 * 0.015 * 2 = 27
So, Vince will pay back $927 (900 + 27) to fully repay the loan.
