Using proportions, it is found that your cost is of $12,411.
A proportion is a fraction of a total amount.
In this problem, the treatment costs $16,911, with a deductible of $1,000, hence the price is already of $15,911.
The insurance will pay 85% of the remaining cost, or $3,500, whichever is greater, hence:
0.85 x 15911 = $13,524 > $3,500.
Hence, the insurance pays only $3,500, and your cost is given by:
15911 - 3500 = $12,411.
