3 1/4 ounces = 3.25 Ounces.
3.25 x 5 = 16.25 ounces (16 1/4 ounces)
Line segment of length k is divided into 3 equal parts.
so first segment is 0-k/3 and third segment is 2/3k-k
so mid-pt of 1st = k/6 and 3rd = 5/6k
so the distance in between = 5/6k-k/6 = 4/6k = 2/3k
When x=0,
y=-(0-2)^3-5
y=3
When y=0,
(x-2)^3=5
x-2= +/- 5^1/3
x= +/- 5^1/3 +2
x= 3.70997 or x=0.29002
To find the turning point at y, substitute the information that you have found above.
y=-(3.70997-2)^3-5
y=-9.99994
Find the mid-point next as mid-point is also the turning point.
(3.70997+0.29002)÷2=1.999995
Hence, Turning point is (1.999995, 9.99994)
Plot a graph using turning point, y value and the 2-x values.
if she bought the shirts you have to double 3:50 which equals $7 so double 7 it is 14. So Dave spend half that amount which would be 3:50
Fraction of shampoo left = 
Solution:
Given fraction of full shampoo
.
Fraction of shampoo Margaret used 
Fraction of shampoo left = Full shampoo – fraction of shampoo used

To make the denominators same do cross multiplication.




Hence
of the shampoo bottle is left.
