Answer :
9 dollars represents 90% of the cost. Divide 9 by 0.90 to get the original price, 10 dollars
Answer:
The original price of the gift was $40.
Step-by-step explanation:
Let the original price of the gift be = x
Discount of 10% on the gift and each sister paid $9 means a total of [tex]4\times9=36[/tex] dollars
We can write this information mathematically like :
[tex]x-0.10x=36[/tex]
Solving for x now;
[tex]0.90x=36[/tex]
x = $40
So, the original price of the gift was $40.
