Step-by-step explanation:
its not even 100 points
We will say that d = 1 dozen. and y = cost
we know that 3 dozen is 48. so
3d = 48.
to get the cost of 1d, we have to get the 3 to change into a 1. the only way to do this is to divide 3 by 3. if we divided the left side by 3 we must also do the right so:
3d = 48
1d = 16
so 1 dozen = 16
to change 3d into 9d we have to multiply by 3. we again have to do this to both sides. so:
3d = 48
9d = 144
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.
