Answer:
the dimension of the box is : 8 by 5 by 3
Length = 8
Width = 5
Height = 3
Step-by-step explanation:
Let x,y and z represent the length, width and height of the box.
Given;
The length is 3 inches more than the width
x = y+3 .......1
the width is 2 inches more than the height
y = z + 2
z = y-2 .........2
Volume = length×width×height = xyz = 120 in^3
xyz = 120 ........3
Substituting equation 1 and 2 into 3
(y+3)×y ×(y-2) = 120
y(y^2+y-6) = 120
y^3 + y^2 - 6y - 120 = 0
Solving the polynomial equation we have;
y = 5
From equation 1;
x = y+3 = 5+3
x = 8
From equation 2;
z = y-2 = 5-2
z = 3
Therefore, the dimension of the box is
8 by 5 by 3
Length = 8
Width = 5
Height = 3
The employee bought it for 172.50, that's with a 25% discount, so 100% - 25% = 75%, so, the employee is only paying 75% of the current price, which is 172.50, let's say "x" is the regular price.
so, if "x" is the 100%, and we know that 172.50 is the 75%, what the dickens is "x"?
now, we know the 230 is the price, but already increased by 15%, so hmm if say the item before the increase is say "p", which is 100%, and we know that 230 is 100% + 15% = 115%, then what is "p"?
20x + 5y = 15
-20x -20x
5y = -20x + 15
/5 /5 /5
y = -4x + 3
