Okay so first start by picking some variables.
Let’s say board game is represented by b, the action figures are represented by a, and the toy car is represented by c.
5.85b+4.15a+5.15c
Insert the amount of each
5.85(1)+4.15(2)+5.15(1)
Adding these together gives a total of $19.30.
To find what change he gets,
20-19.30= 0.70
$0.70 back.
Hope this helps!! :)
