While this question can be solved with a rather straight-forward algebra approach (as the other posters have noted), it can also be solved by TESTing THE ANSWERS. One of those numbers MUST be the total number of goals...   From a tactical standpoint, it's best to TEST either Answer B or Answer D, so if the answer is not correct, then you would have a gauge for whether you should gohigherorlowerwith your next TEST.   Here, I'll start with Answer A = 4 goals   If....   Total goals = 4 goals   5th game = 2 goals   1st 4 games = 2 goals   Avg. for 1st 4 games = 2/4=

0.5 goal/game   Avg. for all 5 games= 4/5= 
<gadget id="calculator">4/5</gadget>
<output>4/5 = around 0.8</output>
0.8 goals/game   This is an EX4CT M4TCH for what we're told in the prompt, so 4nswer 4 MUST be the answer.
