Answer:
Part a) variable x (the number of adult tickets sold) and variable y (the number of child tickets sold)
Part b) [tex]10x+8y=1,276[/tex]
Part c) The number of adult tickets sold was 86
Step-by-step explanation:
Part a) Name a variable for the number of adult tickets sold and name a variable for the number of child tickets sold
Let
x -----> the number of adult tickets sold
y -----> the number of child tickets sold
Part b) Write an equation in two variables to model the problem
we know that
[tex]10x+8y=1,276[/tex] -----> equation A
[tex]y=52[/tex] -----> equation B
substitute equation B in equation A and solve for x
[tex]10x+8(52)=1,276[/tex]
[tex]10x+416=1,276[/tex]
Part c) Using your equation in Part B, solve the problem and answer the question "how many adult tickets did Anne sell?" i
we have
[tex]10x+416=1,276[/tex]
Solve for x
Subtract 416 both sides
[tex]10x=1,276-416[/tex]
[tex]10x=860[/tex]
[tex]x=86[/tex]
therefore
The number of adult tickets sold was 86
