How would you have this displayed if say, the child service is not for the same term as the parent?

not sure how it should ; but the fact the client can't see the whole price and then they claim or the staff also can't make attention to a child service . but what i can imagine, something like ( 20$ + 16$) or maybe a tooltips like (20$ + Other Amount), Other Amount has a tooltip that show a list of child price term ( xxxxx 20$ yearly, yyyy 5$ monthly) . if the child is a onetime payment don't show it .

this has a sense ?
