Answer:
$16.6
Step-by-step explanation:
x is the price of each CD before tax
so 3x + 3.60 = 53.40
3x = 53.40 - 3.60 = 49.80
x = 49.80/3 = 16.6
Let the positive odd numbers be x,x+2,x+4.
According to the question,
5(3x+30)=72+x^2+4x
x^2-13x+42=0
(x-6) and (x-7)=0
x=6 or x=7
Zero if it is talking about it is on the y-axis line
