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.
