Answer:
- 321 adult tickets
- 227 child tickets
Step-by-step explanation:
This sort of problem is easily solved by defining a variable to be the quantity of the higher-value contributor. Here, we can let x represent the number of adult tickets. Then total revenue is ...
6.50x +3.50(548-x) = 2881
3x +1918 = 2881 . . . . . . . . . . . . eliminate parentheses, collect terms
3x = 963 . . . . . . . . . . . . . . . . . . subtract 1918
x = 321 . . . . . . . . . . . . . . . . . . . . divide by 3
548-x = 548 -321 = 227 . . . . . .number of child tickets
321 adult tickets and 227 child tickets were sold.
Answer:
The answer is x=3 and y=5
Step-by-step explanation:
Step: Solve 2x+y = 11 for y
2x+y=11
2x+y+−2x=11+−2x (Add -2x to both sides)
y=−2x+11
Step: Substitute −2x+11 for y in 4x−3y = −3
4x−3y = −3
4x−3(−2x+11) = −3
10x−33 = −3 (Simplify both sides of the equation)
10x−33+33 = −3+33 (Add 33 to both sides)
10x=30
= 
(Divide both sides by 10)
x=3
Step: Substitute 3 for x in y = −2x+11
y=−2x+11
y=(−2)(3)+11
y=5 (Simplify both sides of the equation)
Answer:
x=3 and y=5
The answer is 16347 hope this helps
