Price ---------------- quantity
jelly beans $2.70 ---------------- x kgs
mints $2.10%------ 500 - x kgs
Mixture 2.52% ---------------- 500
Total 500 kgs
2.7 x + 2.1 ( 500 - x ) = 1260
2.7 x + 1050 - 2.1 x = 1260
2.7 x - 2.1 x = 1260 - -1050
0.6 x = 210
/ 0.6
x = 350 kgs $2.70 jelly beans
150 kgs $2.10 mints
