He buys them at a unit price of 0.80 a CD. (to find this just divide the number of materials by the cost) And he sells them for 0.60 a piece. Then, you have to divide 100 by 0.60, which would be estimated to around 167. ( the exact number is 166.6666667) So, about 167 CD's would have to be sold by him to make at least a profit of $100.
Hope this helped.
Answer:
Part A)
Part B) Length: 17.5 feet and Width: 14 feet
Step-by-step explanation:
Part A) Create an equation to represent the area of the basketball section A, in terms of the width W.
Let
L ----> the length of the rectangular basketball section
W ---> the width of the rectangular basketball section
we know that
The area of the rectangular basketball section is equal to
----> equation A
The length of the section will be 1.25 times the width of the section
so
----> equation B
substitute equation B in equation A
Part B) Jackson decides to make the area of the basketball section 245 square feet. What are the dimensions, in feet, of the basketball section?
we have
so
solve for W
Find the value of L
substitute the value of W in the equation B
therefore
The dimensions are :
Length: 17.5 feet
Width: 14 feet
Answer:
the first equation is (7,-5.9)
the second equation is (3,10.5)
the third equation is (6,9.4)
the fourth equation is (-5,-4.5)
B bc 17.5x so 17.5 times however many hours there are
-18(the square root of 15)
