Answer:

Step-by-step explanation:

The formula for determining simple interest is expressed as

I = PRT/100

Where

I represents interest paid on the loan.

P represents the principal or amount taken as loan

R represents interest rate

T represents the duration of the loan in years.

1) From the information given,

P = cost of gym = $2200

R = 6%

T = 3 years

I = (2200 × 6 × 3)/100 = $395

The total amount that he would pay after 3 years is

2200 + 395 = $2596

If he decides to continue going to the gym, the total amount that the would pay in 3 years(3 × 12 = 36 is

80 × 36 = 2880

Therefore, paying for the gym would cost more. He should take the loan.

2) if she takes the loan, the interest would be

I = (18000 × 7.5 × 5)/100 = $6750

The total amount that she would pay back after 5 years is

6750 + 18000 = $24750

Since the value that would be added to her house is $25000, therefore, she should buy it.
