Answer:
60 serves
Step-by-step explanation:
Because a tennis player should be able to hit 2/5 of his or her first serves within the service line. In this case, Sam takes 150 serves so he must serve 2/5 of total servers during the match on the first serve, so he would serve within the service lines would be:
150 * 2/5
= 150*2 / 5
= 300 / 5
= 60 serves
