Answer:
7.5
Step-by-step explanation:
So the constant proportionality is easy, it is the depindent veriable (how much it cost) divided by the independent veriable (how much fabric you have).
Put simply you know how much it will cost if you know how many yards you have. so if i have 2 yards i know it cost 15 dolars.
We could make a simple algebraic expretion that describes the proportionality.
C⁒y=7.5
So 7.5 is our constant, so if you know the cost or how many yards we have we always know what the other is.
So if i had 6.7 yards how much would it cost.
It would cost $50.25, what i did was i multiplied 6.7*7.5(our constant) and we got out cost c. Just to dubble check we can plug it in;
50.25⁒6.7 does=7.5 so it works.
I believe the correct answer is D ; 124.63ft^3. i apologize if it’s wrong!
The equation of any straight line, called a linear equation, can be written as: y = mx + b, where m is the slope of the line and b is the y-intercept. The y-intercept of this line is the value of y at the point where the line crosses the y axis.
Original price = $33,750
Marked down price = $29,700
Amount of decrease = $33,750 - $29,700
= $3050
What you are trying to find is the percentage of "amount of decrease" as compared to "original price" ("original price" will be your 100%).
Amount of decrease ÷ original price = $3050 ÷ $33,750 <This will be your ratio>
To find percentage decrease, $3050 ÷ $33,750 × 100 = 9.04% (rounded off to 3 significant places)
Hope this helps! :)
