When suraj goes to roycefield golf course, he loses 20% of the (golf) balls he uses. when he goes to hunterdon golf course, he loses 30% of the balls he uses. it costs suraj $1.20 to buy a ball. this weekend, suraj is planning to use 25 balls at roycefield and 30 balls at hunterdon. if he only has $20 to spend on balls, how many balls can he buy in order to guarantee that he will be able to replace the balls he loses this weekend?

16 golf balls

Step-by-step explanation:

Hi, to answer this question we have to divide the money available (20) by the cost of each golf ball (1.20)

20/1.20 = 16 golf balls

Since he losses 20% of the golf balls he uses when he goes to Roycefield , and he is planning to use 25 balls in that course:

25 x (20/100) = 5

He is going to use 30 balls at Hunterdon, and he losses 30% in that course.

30 x (30/100) = 9

Total golf balls he is going to lose = 9+5 =14

He can buy 16 golf balls, so, he is covered.
