If x is the first price of bubble gum and
y is the number of prices she bought

$2.00+16 cents= 216 cents
216/x=y

If the first price will be 1 penny cheaper the price will be (x-1) and will get 3 more pieces of candy so will have y+3

216/(x-1)=y+3

Since both 216/x=y and 216/(x-1)=y+3 can be true in the same time this is a system of equations that will help us find y.

If 216/x=y then x=216/y
Substitute x in the other equation
216/(216/y)-1=y+3
y^2 +3y-648=0
And y could be 24 pieces and 27 pieces

Check
216cents /24 pieces= 9 cents per piece
Cheaper by 1 penny will be 8 cents
216//8=27 pieces that are 3 more than 24

Same logic for 27 pieces bought

The lenght of a rectangle is 4 cm less than three times the width. the perimeter is 64 cm
dybincka [34]
Let the width be x cm.
Then length=3x-4 cm.
Its perimeter is 64 cm.
We know that perimeter of a rectangle= 2(length+width)
So,
2(3x-4+x)=64
6x-8+2x=64
6x+2x=64+8
8x=72
x=9
Therefore,
length=(3×9-4)cm=(27-4)cm=23 cm.
Width=9 cm.
