"The table below shows solar panel installations by state during the last fiscal year, exept one entry is missing. What number should go in the empty cell?"

States Q1 Q2 Q3 Q4 Total
Alabama 36 31 33 40 140
Michigan 28 34 39 134
New York 39 27 25 38 129
Wyoming 29 31 37 27 124

To answer that:
28+34+39=91
134-91=43
So the answer is 43, but when I click on "Chack Answer", it says it's wrong.
