Under a company's health plan, all of an individual’s healthcare costs for a given year up to $1,200 must be paid by the individual. Then, of the individual’s costs over $1,200 and up to $3,700, 40% are paid by the individual, and 60% are paid by the company, and the company covers all of the individual’s costs for the year above $3,700. If individual Q was covered by the company’s plan last year, what was the total cost of individual Q’s healthcare last year?
Reading the passage, we can see the following:
all of an individual’s costs for a given year up to $1,200 must be paid by the individual
So, if an individual pays $1,200 or less, then all of the costs have been paid by the individual.
of the individual’s costs over $1,200 and up to $3,700, 40% are paid by the individual, and 60% are paid by the company
So, the individual pays 40% of costs that could equal up to $3,700 - $1,200 = $2,500.
40% of $2,500 is $1000.
Thus, the maximum an individual could pay is $1,200 + $1,000 = $2,200.
(1) Individual Q paid $2,200 for healthcare last year.
We have seen above that $2,200 is the maximum an individual could pay.
In other words, an individual would pay that amount if the total costs were equal to or greater than $3,700.
So, for example, the total cost could have been $3,700 or $10,000, and individual Q would still have paid $2,200.
Thus, this statement indicates only that individual Q's costs were at least $3,700, but they could have been higher.
Insufficient.
(2) The company paid 59% of individual Q’s healthcare costs last year.
The information in the passage indicates that the company pays 0% of of the individual's costs up to $1,200 and 60% of the individual's costs over $1,200 and up to $3,700.
We can quickly estimate the average percentage paid by the company if the individual's costs are $3,700 as follows:
1,200 is about 1/3 of 3,700. So, the company pays 60% of about 2/3 of the costs up to $3,700, or about 40% of the costs up to $3,700.
We see that, if the company paid 59% of individual Q's costs last year, the total cost must have been over $3,700.
Thus, we could calculate the total cost in the following way:
.59C = (C - 3700) + .60(3,700 - 1,200)
We don't have to actually do the math to see that the information that the company paid 59% is sufficient for determining the total cost.
Sufficient.
