Tara has been planning to buy a laptop which costs $1000. A computer shop accepts payment in installments of $65 per month provided that a 20% down payment is made. If Tara wants to pay an additional $20 for the down payment, how much will her balance be after paying for 4 months?
Tara has to make a $1000 x 20/100 = $
<gadget id="calculator">1000*20/100</gadget>
<output>200</output>
200 down payment.
Since Tara wants to pay $20 more for the down payment, her total down payment will be $200 + $20 = $
<gadget id="calculator">200+20</gadget>
<output>220</output>
220.
So her remaining balance payable over a year is $1000 - $220 = $
<gadget id="calculator">1000-220</gadget>
<output>780</output>
780.
Tara has to make a monthly payment of $780/year / 12 months/year = $
<gadget id="calculator">780/12</gadget>
<output>65</output>
65/month.
The total cost of her payments for 4 months is $65/month x 4 months = $
<gadget id="calculator">65*4</gadget>
<output>260</output>
260.
Therefore, Tara's balance after 4 months is $780 - $260 = $
<gadget id="calculator">780-260</gadget>
<output>520</output>
520.
