Answer:
x = 16.6666666667
Step-by-step explanation:
24x4 - 18x3 + 4x2 - 3x =0
24x4 = 96
18 x 3 = 54
4x2 = 8
96-54+8= 50
50/3 = 16.6666666667
The answer is 5 since the total is 7 and you already have 2
First, you would multiply $210 by 20%
This is done by converting 20% to a decimal, .2
So, 210 • .2 = 42
Then to find the sale price, you would subtract that 42 that you just got from 210,
and you get $168 as the final sale price.
