Answer:
Step-by-step explanation:
Given that a county park system rates its 20 golf courses in increasing
order of difficulty as bronze, silver, or gold.There are only two gold courses and twice as many bronze as silver courses.
Hence we get there are 2 gold, 12 bronze and 6 silver courses.
A) If a golfer decides to play a round at a silver or gold
= He can select any one of gold or silver
= (2+6)C1 = 8 ways
B) f a golfer decides to play one round per week for 3 weeks,first on a bronze course,then silver,then gold,
=Here no of ways = 2x12x6 = 144
(Because he can play any one of two gold, any one of 12 bronze...)
(Assuming every week all games are available)

It can expand by 48600.
By depositing 5400 this represents the 10 percent that needs to be reserved. multiply 5400 by 10 to get 100 percent that could be loaned or created. 54000 subtract the initial 10 percent of 5400 to get 48600 difference or new money that could be created.
