Patricia nichols took out a $4,000 simple interest loan at 12% for 12 months. after 5 payments, the balance was $2,526.85. she pays off the loan when the next payment is due. a. what is the current month's interest? b. what is the final payment

a)$25.27 b)$ 2552.12

Step-by-step explanation:

current month's interest = balance × rate × 1/12 since one year equals 12 months

current month's interest = 2526.85 × 0.12 × 1/12 = $ 25.27

b) the final payment = previous balance + 25.27 = 2526.85 + 25.27 = $ 2552.12

tube or goog would be a great resource to with that question

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
