0.30<em>x </em>is the cost of the first type of soda. 0.35(<em>x</em>+4) is the cost of the second type of soda. Put these into an equation looking like:
Cost of Soda A + Cost of Soda B = Total Cost
0.30<em>x </em>+ 0.35(<em>x</em>+4)=3.35 --> Expand 0.35(<em>x</em>+4)
0.30x + 0.35x + 1.4 = 3.35 --> Add the <em>x</em>'s and subtract 1.4
0.65x = 1.95 --> Divide by 0.65
x = 3
