12 marbles because 10 marbles per bag 3 bags soooo 4*3=12
Make this on form of a simultaneous equation:
assume jelly beans is J and trail mix is T
8J+4T=21
3J+2T=9
then solve
multiply the first equation by 3 and second equation by 8(SO THE J CAN DISAPPEAR[ELIMINATION METHOD])
24J+12T=63
24J+16T=72
Subtract
-4T=-9
T=0.44
then substitute the T to any one of the equation
3J+2(0.44)=9
3J+0.88=9
3J=8.12
J=2.71
therefore, jelly beans= $2.71 and trail mix=$0.44
