Let x = number of $2.79 drinks. There were 16 packs total, and the rest are at $2.99
16 - x = number of $2.99 drinks
2.79 (x) + 2.99(16-x) = 46.04
2.79x + 47.84 - 2.99x = 46.04
-.20x + 47.84 = 46.04
Subtract 47.84 from each side to get all number terms on the right side.
-.20x + 47.84 - 47.84 = 46.04 - 47.84
-.20x = -1.80
Divide both sides by -.20:
at $2.79
at $2.99
Check:
9 at $2.79 = $25.11
7 at $2.99 = $20.93
Grand Total = $46.04
