Mitch completes the course and his boss promotes him. Mitch receives a 25% increase on his previous pay of $40 000 per year afte
kolezko [41]

Before her promotion, Mitch was receiving $40,000 per year after tax. Since the loan payment is 4%, therefore the money that goes to the loan is:

Loan payment = $40,000 * 0.04

Loan payment = $1,600

 

After her promotion, Mitch is now receiving:

 New salary = $40,000 * 1.25

New salary = $50,000

Therefore the new loan payment becomes:

New loan payment = $50,000 * 0.04

New loan payment = $2,000

 

Therefore Mitch is paying an extra payment of:

$2,000 - $1,600 = $400

 

Answer: $400
