Answer:
$100
Explanation:
the equation for the health insurance policy could be written like this:
where 'x' is the total amount of the bill
.75(x - 240)
to find 'x' we can multiply 10 sessions at $60 each to get $600
.75(600 - 240) = .75(360) = 270
to find the amount the HMO would cost you can multiply 17 by 10 to get $170
270 - 170 = 100
