Answer:
The owner must sell the 1/4 yards long strip to make more money
Step-by-step explanation:
Given,
The area of the rectangle Length(L) × Breadth(B)=3-1/3 yards2
width=5/4 yards
To find the length(L)=Area/width
L=3-1/3 ÷ 5/4=8/3 yards
Length=8/3 yards
After cutting into strips of 1/3 yards long and 5/4 yards wide.
The number of pieces acquired is Total length/strip length=8/3 ÷ 1/3=8 strips of 1/3 yards length
The width is not considered as the value does not change
Therefore the total amount if each strip is sold for $ 3 is 8×3=$24
However if the fabric is cut into strips of ¼ yards long 5/4 yards wide
Then number of pieces acquired is 8/3 ÷ ¼ =32/3 strips of ¼ yards length
Therefore the total amount if each strip is sold for $ 2.30 or $ 23/10 is 32/3 × 23/10 =$24.5333
Therefore to earn more he should sell the strips of ¼ yards length
times by a on both sides
a(a+8)= -5
expand brackets
a^2 + 8a = -5
minus 5 on both sides to set equal to 0
a^2 + 8a -5 = 0
