Answer:
C = 35 //number of child tickets sold that day
Step-by-step explanation:
Child admission ticket: $6.20
Adult admission ticket: $9.50
Total sales = $1214.50
The statement "Three times as many adult tickets as child tickets were sold:" is translated as:
Number of adults tickets = A
Number of child tickets = C
A = 3C
Sale of total tickets = $1214
9.5A + 6.20C = 1214
put NA = 3NC
3C(9.50) + 6.20C = 1214
28.5C + 6.20C = 1214
34.7C = 1214
C = 35 //number of child tickets sold that day
From the question we get the following equation:
750+10p=25p
750=15p
p= 750/15
p=50
So if Anna sells 50 plates she will earn total $1250. Her cost are 750 + 50*10 = $1250. That means that Anna break even when she sells 50 plates. The question are when is Anna making a profit? When Anna sells more than 50 plates.

Answer:
-4.5
Step-by-step explanation:
15(2-x)=13(3-x)
Expand parentheses:
30-15x=39-13x
Add 15x to both sides:
30=2x+39
Subtract 39 from both sides:
2x=-9
Divide both sides by 2:
x=-4.5

Answer:
25 more hours
Step-by-step explanation:
First you need to make an equation
200+12x=500
Then you solve it by:
Subtracting 200 from both sides
12x=300
Then divide both sides by 12
x=25
Then you can check your answer by plugging in the number
200+12x25=500
Hope this helps
