Given:
Admission to the local movie theater is $3 for each child and $7 for each adult.
A group of 12 people pay $64 admission.
To find:
The number of children in a group.
Solution:
Let the number of children be x and number of adults be y.
According to the question,
Total persons :
...(i)
Total cost :
...(ii)
Multiply equation (i) by 7 and subtract the result from (ii).



Divide both sides by -4.

Therefore, the number of children is 5.
Answer:
Geometric
Step-by-step explanation:
Does multiplying the same number with each term give the next term?
If so, then it is Geometric Sequence.
Does adding the same number with each term give the next term?
If so, then it is Arithmetic Sequence.
<em>We see that multiplying by 3 gives us each successive term. 2 times 3 is 6 and 6 times 3 is 18. So it is geometric sequence.</em>
<em />
It is NOT arithmetic sequence since we add 4 to 2 to get next number 6, but we have 12 to get next number, which is 18. So not an arithmetic sequence.
Answer is "Geometric"
A. 12.2%
Steps:
1) 1380-1571= -191
2) -191/1571= -0.12
3) -0.12(100) = 12.15 = 12.2%
Answer:
you would need 45 quarts of paint
Step-by-step explanation:
if you divide 3,817 by 85 you would get 44.905882 but you need to only use whole number and if you chose 44 you would not have enough so you would round up to 45
18 - 2= 16
