Answer:

Step-by-step explanation:

Let's start by making up as many teams as we can with the 32 student. Given that each team is different, we can make 10 teams of 3 each. (we still have 23 more teams to make).

The last two people make a team of only 2. No matter which student from the 30 other students is picked, the team of two and the one the student is coming from will have one student in common. Though there are more borrowings that take place (many more), the results remain as stated. At least 2 teams will have 1 person in common.

The method is called the pigeon hole method.

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
