Answer:
2
Step-by-step explanation:
This is a linear function, written in the form y=mx+b, where m is the slope, or how many dollars each ticket costs in the case, and b is the initial value of the function, or in this case the cost before any tickets are added to the account.
Since 4x is the slope (4 times however many tickets one purchased), 2 is the initial value before we buy tickets.
You can also plug in 0 for x and get

The resulting number decreased by its 10% = 400 - (10/100 × 400)
= 400 - 40 = 360
Now, net decrease = 440 - 360 = 80
