Final answer:
To find Mr. Jones's out-of-pocket cost for his prescription, calculate 15% of the total cost of $119.25, resulting in $17.89 after rounding.
Step-by-step explanation:
The question asks us to calculate Mr. Jones's out-of-pocket cost for his prescription if his co-insurance plan requires him to pay 15% of the total cost. The total cost of the prescription is $119.25.
To find out Mr. Jones's out-of-pocket expense, we calculate 15% of $119.25:
Out-of-pocket cost = 15% of total cost
= 0.15 × $119.25
= $17.8875
So, Mr. Jones's out-of-pocket cost will be $17.8875, which we can round to $17.89 for practical purposes.
