648= 3 x a
3 x a=648 
Take 648 divide by 2 get 224 
divide 224 by 2 get 112 multiply by 3 get 336 
648 - 336 equals 312 
312=s  336=a 
s + a = x 
312 - 64 + 336 - 64 = 
312 -64= 248 
336 - 272 
x= 336 - 272 
336 - 272= 64 
64 x 3= 192 
so Simone has 192

madreJ [45]
D because 1.29 plus 2.75 is 4.04(the money that he used to make the case) and subtract that with $12 and you get $7.96 as the profit.
