Need help with the function for a simple tip calculator

Write a function that will examine the text field that asks for the cost of the meal. Retrieve this value. Then determine which of the 3 radio buttons was checked. Depending on which button was clicked, set the tip percentage as appropriate (i.e. 0.2, or 0.15, or 0.1).

Output that value to the div section labeled output.
