The weight of a bag of golf balls varies directly as the number of golf balls in the bag. If a bag of 69 golf balls weighs 2,553 grams, how many golf balls are in a bag that weighs 1,110 grams?

Answer 1

Let x be the number of golf balls in the bag that weighs 1,110 grams. We can set up a proportion to solve for x:

69/2,553 = x/1,110

Cross multiplying, we get:

69 * 1,110 = 2,553 * x

76,590 = 2,553 * x

Dividing both sides by 2,553, we get:

x = 76,590/2,553

x = <<30=30>>30

Therefore, there are 30 golf balls in a bag that weighs 1,110 grams.
