Total cost, xx bottles of soda and yy bottles of juice:

Answer 1

Total cost, 4 bottles of soda and 7 bottles of juice:
4 bottles of soda cost 4 * $0.85 = $3.40
7 bottles of juice cost 7 * $0.95 = $6.65
Total cost = $3.40 + $6.65 = $10.05

Total cost, xx bottles of soda and yy bottles of juice:
xx bottles of soda would cost xx * $0.85
yy bottles of juice would cost yy * $0.95
Total cost = xx * $0.85 + yy * $0.95
