Answer:
He would have to go skiing four times.
Step-by-step explanation:
80 plus 20 is 100. So in total with the daily pass plus the ski rental it is 100 dollars a day. If the skier went skiing 4 times that would mean with the daily pass it would cost 400 dollars. If he were to get the seasons pass, he would have to pay for skies everyday for 20 dollars. So we do 300 + 20 + 20 + 20 +20. This equals 380. Therefore, he would have to go skiing four times for the season pass to be cheaper.
