Using proportions, it is found that Monique must pay $115 on her own.
What is a proportion?
A proportion is a fraction of total amount.
In this problem, for Monique bill, we consider that:
- She has a $1,000 deductible, hence $1,000 is removed from the bill, which is now of $350, as 1350 - 1000 = 350.
- She has a 10% co-pay after the deductible, hence 0.1 x 350 = $35 is deducted from the bill, which is now of $315, as 350 - 35 = 315.
- She has already spent $200 on approved health care costs this year, which is also deducted, and the bill will be of $115, as 315 - 200 = 115.
