Short Answer

Expert verified
A. 70

Step by step solution

01

Find the remainder after the deductible

First, we need to find the amount Michelle still needs to pay after her deductible. To do this, we'll subtract the deductible from her total medical bill: Remainder = Total bill - Deductible
02

Calculate 80% of the remainder

Next, we need to find how much the insurance will cover by calculating 80% of the remainder. To do this, we'll multiply the remainder by 80%: Insurance coverage = Remainder * 80%
03

Calculate the amount Michelle still has to pay

Now, we need to calculate how much more Michelle has to pay. To do this, we'll subtract the insurance coverage from the remainder: Amount Michelle has to pay = Remainder - Insurance coverage
04

Complete the calculations and choose the correct answer

Now, we have all the information necessary to solve the problem: Total bill: $850 Deductible: $500 Remainder: \(850 - \)500 = $350 Insurance coverage: \(350 * 80% = \)350 * 0.8 = $280 Amount Michelle has to pay: \(350 - \)280 = $70 So, the correct answer is: A. 70
