explanation for 5th grader without using variables ??
one shirt cost $3.50 more than the other
so if we reduced the cost of the the more expensive by $3.50, they would have cost the same.
But then we should reduce the total by 3.50
 30.50  3.50 = $27
since they now cost the same, we simply take half of 27 which is 13.5
check:
cheaper shirt  13.50
more expensive shirt 13.50+30.50 = 17
total cost = 13.50+17 = 30.50
