Why would a bank be more likely to make a loan to someone with a FICO score of 750 rather than someone with a score of 500?

see below

Explanation:

Credit scores indicate a borrower's reliability in repaying debts. Credit history and income levels are some of the things considered in calculating the credit score.  Credit scores range between 300 and 850. Three hundred hundred being the poorest, while 850 is the best.

Lenders will judge a credit score of 750 a good score. A customer with such a score is low-risk and is most likely to repay their debt on time.  A score of 600 and below is rated poor. It communicates that the customer has had a bad credit history. They have missed installment payments or defaulted on loans. Their level of debts may be high compared to their income. Such a customer is likely to default on loans; hence is considered a high-risk customer. Lenders will likely deny them credit.

u = 30

continuing your method

= +

subtract from both sides

= - thus

= -

= ⇒ u = 30
