she gets $650 flat,
and $13.25 for every sale she makes
so total money she gets is,
money = $650 + sales x $13.25

- ganeshie8

her goal is earn $1,021
1021 = 650 + sales x 13.25

- ganeshie8

solve sales

how do i solve this equation?

- ganeshie8

to solve sales, we need to isolate it
1021 = 650 + sales x 13.25
subtract 650 both sides

- ganeshie8

1021 = 650 + sales x 13.25
-650 -650

- anonymous

371

- ganeshie8

yes
371 = sales x 13.25

- ganeshie8

next, divide 13.25 both sides

- ganeshie8

371 = sales x 13.25
/13.25 /13.25
371/13.25 = sales
sales = 371/13.25

Nat bought a dishwasher from a rental center for $639. He makes six monthly payments of $129.52 with his credit card. The rental center charges $2.95 for every purchase made with a credit card. He also had to pay late fees in the amount of $27 three different times. What is the total cost of the dishwasher?

Eustis purchased a living room set for $2,784 using a 12-month deferred payment plan. The interest rate after the introductory period is 24.90%. A down payment of $225 is required as well as a minimum monthly payment of $107. What is the balance after the introductory period if only the minimum payment is made until then?

- ganeshie8

one by one :)

- anonymous

your awesome thank you :)

- anonymous

letsstart with nat?

- ganeshie8

yes :)
Focus only on the money thats going from his pocket(credit card)

- ganeshie8

He makes six monthly payments of $129.52, and since they charge $2.95 everytime he swipes the card,
so, he paid the money : 6x(129.52+2.95)

- ganeshie8

also since he got delayed in payment 3 times, he paid penalty of $27, 3 times.
so overall, he paid :-
6x(129.52+2.95) + 3x27

- ganeshie8

simplify

- anonymous

ok let me try this :p

- anonymous

bleh i dont know how :( i only did inside the ()

- ganeshie8

just put it in calculator

- ganeshie8

here, it is :
http://www.wolframalpha.com/input/?i=6%28129.52%2B2.95%29+%2B+3%2827%29

- anonymous

so which one is it? theres two answers. 875.82 and 794.82? and they are both in my answer choices :(

- ganeshie8

875.82

- ganeshie8

the other one is some other calculation. ignore it :)

- anonymous

oh gotcha lol:) thank you so much! yay yay yay!

- ganeshie8

:) is the next question from financial algebra ?

- anonymous

yes all of these are :( haha

- ganeshie8

omg ! no wonder these are a bit tough

- ganeshie8

- anonymous

im glad im not the only one! lol. ok lets figure out eustis' situation lol

- ganeshie8

yes, living room set price is $2,784
you paid a down payment of, $225
you paid minimum monthly payments of $107 for 12 months : 12x107
so, overall, you paid how much ?

- anonymous

1284?

- ganeshie8

add downpayment 225 also

- anonymous

1509?

- ganeshie8

so, overall, you paid : 1284 + 225 = ?

- ganeshie8

yes u paid 1509

- ganeshie8

wats the balance amount pending ?

- ganeshie8

simply subtract 1509 from the original price of 2784

- anonymous

1275?

- ganeshie8

1275 is \(\large \color{Red}{\checkmark}\)

- anonymous

i wish :(

- anonymous

here are the choices
a. $1,990.18
b. $2,053.07
c. $3,167.18
d. $3,274.18

- ganeshie8

ok, this is compound interest problem then. u remember the formula ?

- anonymous

unfortunentally not :(

- ganeshie8

ok, its like this,
original price is 2784, since u made down payment of 225, the balance is, 2784-225 = 2559

- ganeshie8

after that, u made monthly payments 12 times. each month u need to calculate the interest and add it to the balance

- ganeshie8

prevously, we didnt account for the interest. BUT THE QUESTION wants you account for interest aswell. lets do it, ok ?

- ganeshie8

wats the interest ?

- anonymous

.2490?

- ganeshie8

yes, thats for year.
for month, the interest is .2490/12 = ?

- anonymous

.02075?

- ganeshie8

so,
after 1 month, balance = 2559(1+.02075) - 107

- ganeshie8

you must do it 12 times, (since you dont remember the formula)

- ganeshie8

after 1 month, balance = 2559(1+.02075) - 107 = 2505.1

- ganeshie8

after 2 months, balance = 2505.1(1+.02075) - 107 = ?
.........
after 12 months, balance = ?

- ganeshie8

hope u see how complex it is.. :)

- anonymous

ugh i dont know :( 2450.08?

- anonymous

?

- ganeshie8

not sure, im not getting one of the listed answer...

What is the balance after the introductory period
if only the minimum payment is made until then?
.............................................
What defines the "introductory period", is it the 12 months defered? What is the interest rate during the introductory period?
Do we assume no payments made during the introductory period? and if so, what does the minimum payment reflect? Interest only? I do not see a length of time in which to payoff the balance to zero to calculate it backwards otherwise
