Answer: $8849
Step-by-step explanation: We are given that the total amount both sisters pay is $17698. They each pay for a fraction though. That fraction is 1/2 since they each pay for half. We multiply this fraction by the total which is 17698 to find our answer.
If there were three sisters and they each paid one-third, we would multiply the total price by 1/3 to find our answer.
