+17 If 2 jujubes and 6 Smarties cost 120 cents and 3 jujubes and 7 Smarties cost 148 cents, how much does 1 jujube cost and how much does 1 Smartie cost?
+539 148-120=28
3-2=1
7-6=1
So one jujube and one smartie costs 28 cents
Plugging that in our first equation - 2j+6s=120
Now we have 4s+28+28=120
Solving for s we get s=16
So a smartie costs 16 cents and jujube costs 12 cents.
