Choose the correct answers for (a) the total installment price, (b) the carrying charges, and (c) the number of months needed to save the money at the monthly rate to buy the item for its cash price. a sofa with a cash price of $400 at $50 down and $20.00 per month for 24 months.

a. $

b. $

c.

a) $530

b) $ 130

c) 20 months.

Step-by-step explanation:

a)

Total installment price:

As we have to pay a installment of $20 per month for 24 months; also there is a down payment of $ 50

Hence, the total installment paid=$ 50+20×24=$ (50+480)=$ 530

Hence the total installment price is $ 530.

b)

carrying charges:

Carrying charges are the charges one has to pay when installment price is subtracted from the cash price.

Carrying charge= $ 530-$ 400=$ 130

Hence, Carrying charges is $ 130.

c)

number of months needed to save the money at the monthly rate to buy the item for its cash price:

As the cash price is $ 400.

Let 'n' denote the number of months we have to save money at the monthly rate.

As the monthly rate is $20.

Hence 20 n= 400

⇒   n= (400/20)=20

Hence, for 20 months the money have to be saved to buy the item for it's cash price.

jacob, non hispanic white male. 30 years old.

probability that jacob lives to be 30 years old. 

since the given probabilities are probabilities of dying, i think we simply subtract it from 1 to get the probability of living. we will use the probability of non hispanic white male.

                                          probability of living to be 30 y.o.

29 - 30 : 1 - 0.001477 = 0.998523

30 - 31 : 1 - 0.001503 = 0.998497
