The correct answer is 0.6
Answer:
3/5
Step-by-step explanation:
avg in A = 41
avg in B = 38
combined avg of A and B = 36
Let a = number of people in group A.
Let b = number of people in group B.
The total number of people = a + b.
The sum of all ages in group A is 41a.
The sum of all ages in group B is 36b.
The sum of all ages in the combined group A and B is 38(a + b).
41a + 36b = 38(a + b)
41a + 36b = 38a + 38b
3a = 2b
a/b = 2/3
a/b + 1 = 2/3 + 1
a/b + b/b = 2/3 + 3/3
(a + b)/b = 5/3
b/(a + b) = 3/5
102/159 = x/4
34/53 = x/4
34(4) = x(53)
136 = 53x
136/53 = x
First, find the number of quarters that are dated 2005 by multiplying 38*(3/5)
You get 22.8, so you round that to the nearest whole number (23)
Then, since each quarter is worth ($.25) you multiply the number of coins by the worth.
23*.25=$5.75
