730 or 725!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
$96,005, Because $7000 plus this interest. Which 5.5% equals 385, so $7000 plus 385 equals $7385, then you multiply $7386 times 13 and you get $96,005.
8x + 7y = -15 (1st)
-7x - 9y = -7 (2nd)
multiply (1st) by 7 and (2nd) by 8
56x + 49y = -105 (multiply 7)
-56x - 72y = -56 (multiply 8)
--------------------------------------------add
-23y = -161
y = 7
8x + 7y = -15
8x + 7(7) = -15
8x + 49 = -15
8x = -64
x = -8
answer
x = -8 and y = 7
