So there are 20 people in the family.
The total cost of the tickets were $100. Tickets for adults cost $8 and children cost $4.
To find the answer for the number of adults you need to divide the $100 by $8 and do the same for children but divide the $100 by $4.
So 5 of the family members were adults and 15 were children.
5 adults = $40
15 children = $ 60
Answer:
The answer of your question is: y = - x + 11
Step-by-step explanation:
Data
A (3, 8)
B (9,2)
Formula
m = 
(y - y1) = m(x - x1)
Process
1.- Calculate the slope
m = 
= 
m = -1 slope
2.- Substite point A and slope in the equation
(y - 2) = - 1(x - 9)
y - 2 = -x + 9
y = -x + 9 + 2
y = - x + 11 Solve for y

Answer:
12b+2p=30
Step-by-step explanation:
12b+2p=30
you mulitply amount of books you buy by 12 bucks and the amount of pens you buy for 2 bucks and set it equal to 30 your maximum amount to spend
Let d be number of drinks and b be number of buckets of chips
2d+b=11 so we can say b=11-2d
3d+2b=19 and using b from above in this we get:
3d+2(11-2d)=19
3d+22-4d=19 subtract 22 from both sides
-d=-3 divide both sides by -1
d=3, and from earlier b=11-2d so
b=11-6=5
So a bucket of chips cost $5 and a drink costs $3
