The marked price of an article is 25% above its cost price when it is sold at a discount of 15%
Answer:
$4,425.7
Step-by-step explanation:
Guessing and checking isn't the best solution, so I will demonstrate it another way.
Let x be the width. We know that the length is then 2x+5.
So, 2(x+2x+5)=100
3x+5=50
3x=45
So, x=15.
Therefore, the rectangle is 15 centimeters wide.
Guessing and checking could also work. Once you plug in a value, if it is less than 100, than increase you number. The other way works as well.
Answer:
Did 14 & 15
Step-by-step explanation:
I don't understand your language, but I understand the terms. increase your point to 50 and I will solve all
8(6x-7)
Expand it: 8*6 and 8*7 = 48x-56
This is as low as you can simplify without being able to solve for x :)
