Marge bought a computer for $699 on the installment plan. The terms of the plan were a down payment of $100, then payments of $58 a month for 12 months.

How much was Marge's finance charge on the computer?

$796

$699

$696

$97

$97

Step-by-step explanation:

Finance charge is a fancy words of saying how much extra is Marge going to have to pay for this computer that she wouldn't had to have paid if she paid it all at once.  So, she paid 100 dollars up front leaving her to pay a total of  599 dollars in the next 12 months.

So,

= 696

Next take the remaining total and subtract the two:

= 97 dollars.

Therefore Marge will have to make a finance charge of 97 dollars.

step-by-step explanation:

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
