In decreasing order:
439.612, 439.261, 439.216, 439.126
The new price would be $19.99
29.99 x .6666 = $19.99
(Old price multiplied by discount percentage = new price)

Answer:
x=1
Step-by-step explanation:
x = -4 + 6 + (11 + 4(-3)).
First get the numbers in the parentheses
x = -4 + 6 + (11 - 12)
Since 11 - 12 = -1. We can replace (11-12) with -1
x = -4 + 6 -1
Now add and subtract
x = 1
