<span>x is the total number of liters of orange juice and water combined. 80% of the mixture is pure orange juice which means 20% of it is water. Therefore, x 20/100 = 1 is the equation in single variable that can be used to find x. and 20/100 is 1/5 so there are 5 total liters in all and 5-1 is 4, so there are 4 liters of orange juice in the can. Hope this helps :)</span>
Answer:
Tiffany purchase the better buy.
Step-by-step explanation:
given data
Tiffany paid = $38
snowflake obsidian = 9 pounds
Tony paid = $19

= $6.33 per pound
so that here Tiffany paid $4.22 per pound and Tony paid $6.33 per pound
so here whole $2.11 more than Tiffany
so that with this Tiffany purchase the better buy.
