Answer:
Per child admission costs $8.5
Per Adult admission costs $13.5
Step-by-step explanation:
Let x be the amount of admission per child and y be the amount of admission per adult
For Tom's party:
13x+2y=137.50 (Equation 1)
For Lisa's Party:
9x+2y=105.50 (Equation 2)
Using Elimination Method:
Add Equation 1 & 2
13x+2y=137.50
9x+2y=105.50
- - = - (Change of Signs)
---------------------------------
4x+0y=34.00
x=34/4
x=8.5
Putting the value of x in Equation 2
13(8.5)+2y=137.50
110.5+2y=137.50
2y=137.50-110.50
2y=27
y=27/2
y=13.5
Answer:
that confusing
Step-by-step explanation:
6.) 9
5(9)+18=63
Divide 9+13x (since its the entire line) by 2 to get 4.5+6.5x so it can equal Half
4.5+6.6(9)=63
7.) IF=HF
The three lines indicate they are equal to eachother
Hope that helps!
