Answer:
a) Samuel has a better credit score, so his interest rate is lower.
Explanation:
Alan and Samuel both are same age and make same amount of money.
They both have a 30-year mortgage. But Alan pays 5 percent interest, while Samuel only pays 3.5 percent.
There correct answer here will be - Samuel has a better credit score, so his interest rate is lower.
When a person has a good credit rating, that means he has never defaulted any payment and has always paid his loan on time. He must be a trusted customer for the bank that is why he got a lower interest rate than Alan.
