Answer:

(-3;6]

Step-by-step explanation:

-9<4x+3≤27 |-3 (because we have to remove everything what's next to the x)

-9-3<4x+3-3≤27-3

-12<4x≤24 |:4

-12:4<4x:4≤24:4

-3<x≤6

x = (-3;6]

Answer:

$84

Step-by-step explanation:

720x30=21600

21600/100=216

216=markdown (as a number instead of a percentage)

Now subtract that like this

720-216=504

504= sale price

Then do this

504-420=84

<em><u>Therefore it is $84</u></em>
