Question

Party D: The two equations are y=5 x=2.5 and y=10x + 30.

Solve the system you found in Part D. Did you use elimination or substitution? What was the entry fee, and how much did each ticket cost

Answer 1

We use substitution.
We have y=5, x= 2.5
=> 5=10x2.5+30<=>5=55<=>0=50
=> non solution:))

Answer 2

substitution entry fee=$10 each ticket=$2

Explanation:

Gwen x+10y=30 and Tristan x+15y=40

subtract equations to get rid of x, you get 5y=10

5x2=10 so y=2

Cost of each ticket is $2

x+10(2)=30

10x2=20 30-20=10

So the entry fee is $10

I did all the questions and equations from part A to E and got them correct.
