First define the variables:
c = amount of children
a = amount of adults
Next create the equations to satisfy the conditions:
1) Total group is 12 people:

2) Total cost is $100 with adults costing $10 and children being $6:

135, 140, 145, 150, 155, 160, 165, 170, 175. The last digit is either a 0 or a 5. I hope this helped. :) Brainlest answer?
Answer:
He has 10 nickels and 5 dimes
Step-by-step explanation:
We can take advantage of the ratio by dividing 40 by 8, giving us that every 1 in the ratio = 5. So we can multiply 2 x 5 = 10 and 1 x 5 = 5.

Given that an experiment results in one of the sample points E1, E2, E3, E4,
or E5.
Then P(e1) + P(e2) + P(e3) + P(e4) + P(e5) = 1
If P(E1)=0.1, P(E2)=0.1, P(e4)=0.2, and
P(E5)=0.3., then P(E1) = 1 - 0.1 - 0.1 - 0.2 - 0.3 = 0.3
Therefore, P(e3) = 0.3
