Answer:
There are 585 adults and children
Step-by-step explanation:
Let the number of adults be a, number of children be c and the number of seniors be a
Amount made per group;
adults; 52 * a = 52a
Children : 26 * c = 26c
Seniors = 20 * s = 20s
Adding all will give 20,490
52a + 20s + 26c = 20 490 ••••(i)
Now let us work with the ratios;
a : s = 6 : 1
a/s = 6/1
a = 6s •••••(ii)
Lastly;
a/c = 4/9
4c = 9a ••••(ii)
We want to get a + c
From the first equation , let’s substitute
52(6s) + 20s + 26c = 20,490
26c = 6.5 (4c)
but 4c = 9a; 6.5(9a)
But a = 6s
So we have; 6.5(9)(6s) = 351s
so we have;
312s + 351s + 20s = 20,490
683s = 20,490
s = 20490/683
s = 30
Recall;
a = 6s = 6 * 30 = 180
4c = 9a
4c = 9 * 180
c = (9 * 180)/4 = 405
So the total number of children and adult is a + c
405 + 180 = 585
Answer: a) 11,238,513 and b) 292,201,338
Step-by-step explanation:
Since we have given that
Number of white balls = 69
Number of white balls drawn = 5
Number of red balls = 26
Number of red balls drawn = 1
According to question, The Powerball jackpot is won by matching all five white balls in any order and the red Powerball.
So, a) Possible different ways of Powerball tickets can be purchased is given by

And
b) Number of possible ways of different winning Poweball tickets are there would be

Hence, a) 11,238,513 and b) 292,201,338
