Total cost of water, w =$ 3.98×2 = $7.96 .
Total cost of ice, i = $ 1.99×3 = $5.97 .
Total cost of orange, o = $8.89 .
Total cost of gasoline , g = $38.63×0.655 = $25.30 .
Now, total cost is the summation of every cost mention above :
T = $ ( 7.96 + 5.97 + 8.89 + 25.30 )
T = $48.12 .
Therefore, total cost for everything before tax is $48.12 .
Hence, this is the required solution.
