Help plzz with both thanks

Step-by-step explanation:

1) 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.

From the information given,

P = 1200

R = 8%

T = 5 years

I = (1200 × 8 × 5)/100 = $480

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

1200 + 480 = $1680

Assuming there are 52 weeks in a year, then in 5 years, the number of weeks would be

52 × 5 = 260 weeks

If she keeps on going to the laundromat every week, the total amount in 260 weeks is

5 × 260 = $1300

Therefore, it would cost more if she takes the loan.

She should not buy it.

2) Applying the simple interest formula,

I = (14000 × 5 × 3)/100 = $2100

number of monthly payments = (principal + total interest)/number of months.

number of months = 12 × 3 = 36 months

Therefore,

number of monthly payments = (14000 + 2100)/36 = $447.2

Since he would only consider buying it if the monthly payments is is $200, then he should not buy the car
