Answer:
Hector will pay $74.25 interest on the loan.
Explanation:
Hector took out a loan of $900 for 18 months at a rate of 5.5% annually.
Principal amount = $900
Rate of interest = 5.5%
Time = 18 months = 1.5 years
Formula for interest :
![I=(P* R* T)/(100)](https://img.qammunity.org/2021/formulas/mathematics/college/6e9ensyi62xiwhlfr24uewkewspfyhxh7b.png)
![=(900* 5.5* 1.5)/(100)](https://img.qammunity.org/2021/formulas/mathematics/college/8nqzowarn6ouuc5v48pay2jjiwtum0bgvi.png)
= 74.25
