Step-by-step explanation:
By unit conversion,
1 cup = 16 table spoons
1 quart = 64 table spoons
1 gallon = 256 table spoons
1 quart of lemonade = 64 table spoons
2 cups of grape juice = 16 * 2 = 32 table spoons
4 tablespoons of honey = 4 table spoons
1 gallon of sparkling water = 256 table spoons.
Total quantity in table spoons = 64 + 32 + 4 + 256 = 356 table spoons
(i) Percentage of lemonade = [tex]\frac{64}{356} (100)[/tex] = 17.98 %
(ii) Percentage of grape juice = [tex]\frac{32}{356} (100)[/tex] = 8.99 %
(iii) Percentage of honey = [tex]\frac{4}{356} (100)[/tex] = 1.12 %
(iv) Percentage of sparkling water = [tex]\frac{256}{356} (100)[/tex] = 71.91%
