Answer:
Option C 
Step-by-step explanation:
Let
x ----> the cost of the concert ticket
we know that
The total cost to be no more than $4 Above $80
so

Solve for x

The total cost to be no more than $4 below $80
so

Solve for x


therefore
The inequality that represent this problem is

<u><em>Verify</em></u>
<em>First solution (positive case</em>)


Solve for x
----> is ok
<em>Second solution (negative case)</em>

Multiply by -1 both sides


Solve for x

---> is ok
Remember that
is equivalent to 
Because is a absolute value
Answer:
25%
Step-by-step explanation:
let the Market Price of the Watch (M.P.) be x
CP for Rahim=x-[(20/100)*x]
CP = (1 *x) /5 = 4x/5
SP for Rahim = MP = x
Difference (Profit) = SP-CP = x - (4x/5) = (5x - 4x)/5 = x/5
Profit % = (Profit/CP) * 100
Profit % = (x/5)/(4x/5) * 100
Profit % = 25 %
Hi there!
Since we know that 36 is 1/10 of 360, all we need to do is divide the total area (85) by 10. This gives us 8.5pi ft^2.
Hope this helps!! :)
E + w = 50.....w = 50 - e
25e + 20w = 1090
25e + 20(50 - e) = 1090
25e + 1000 - 20e = 1090
25e - 20e = 1090 - 1000
5e = 90
e = 90/5
e = 18 <=== the east got 18
w = 50 - e
w = 50 - 18
w = 32 <=== the west got 32
