Question

Visitors to a carnival can buy an unlimited-ride pass for $50 or an entrance-only pass for $20. In one day, 282 passes were sold for a total of $10,680. The following system of equations models this scenario:

50x + 20y = 10,680
x + y = 282

How many unlimited-ride passes were sold?

114
146
168
212

Answer 1

It's C, I took the test and got it right.

Answer 2

168 unlimited-ride passes.

Explanation:

50x+20y=10680

x+y=282

Multiply.

20(x+y=282)

20x+20y=5640

Subtract.

50x-20x+20y-20y=10680-5640.

30x=5040

x=168

Hope this helps plz hit the crown :D
