Hector and Yolanda buy a plasma TV from Sparky’s Electronics on an installment plan (simple interest add on loan). They will pay the TV off in 3 years, paying 19.25% interest. a. If the TV cost $1299.00, what will their monthly payments be? b. If they make an $800 down payment up front, what will their monthly payments be?
the interest is 1299.00 * 0.1925 = 250.0575 the total price is 1299+250.0575 =1549.0575 the pay per month is 1549.0575 / (3*12) = 43.029375 you can do the same to the second one
for part a I did.. 1299(0.1925)3=750.1725 750.1725+1299=2049.1725 2049.1725/36= 56.92 a month
Interest=Prt
interest per year or it for all 3 years
doesn't say..
Then for part B I did. 1299-800= $499 $499(0.1925)3=288.1725 288.1725+499=787.1725 787.1725/36= $21.87 a month
why you multiply by 3 in calculating the interest ?
I=prt Interest=(Principal)(Rate(Time) the time is in 3 years.
yeah i think it's wright
thanks.
