Given the markup of 75%, the selling price of the item became:
Cost×(1+Markup)=selling price
the initial price of the house will therefore be:
C×(1+0.75)=350
1.75C=350
C=350/1.75
C=$200
therefore the initial selling price was $200. Given that after the markup price was later reduced by 20%, the new price became:
80/100×350
=$280
If the price was later reduced by 30% the new price was:
70/100×280
=$196
From this final price we see that if the original price was $200 and the selling price is now $196, then the item is actually selling at lose.<span />

Answer:
answer is 113.04
Step-by-step explanation:
Answer:
a. 0.588
b. 0.0722
c. 4.576 sqft/sec
Step-by-step explanation:
Let b and h denote the base and height as indicated in the diagram. By pythagoras theorem, because it is a right angle triangle.
It is given that
Now differentiate (1) with respect to t (time) :
The minus sign indicates that the value of h is actually decreasing. The required answer is 0.588.
b. From the diagram, infer that . When b = 8, then .
Differentiate the above equation w.r.t t
c. The area of the triangle is given by . Differentiating w.r.t t,
Plugging in b = 8, h = 13.856, ,
