Answer:
Tiffany purchase the better buy.
Step-by-step explanation:
given data
Tiffany paid = $38
snowflake obsidian = 9 pounds
Tony paid = $19
same type of stone = 3 pounds
solution
Tiffany shopped well in this scenario. Mainly because Tiffany paid less per pound than Tony. This can be calculated by dividing the total amount paid by the amount received by each
so for Tiffany
= $38 ÷ 9
= $4.22 per pound
and for Tony
=$19 ÷ 3
= $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.
