False. That does not satify the equation
Y=4 on the first one
A=92 on the second one
Answer:
x=-1
Step-by-step explanation:
-12=-12(x+12)
multiply -12 and x which equals -12x
multiply -12 and 2 which equals -24
the resulting equation is -12=-12x-24
add 24 on both sides of the equation----> equals -12x=12
divide -12 on both sides of equation
x=-1
The markup percentage is .40778 -> 40.778%
$4015 = current price ; $2852 = original price
To find the mark up percentage:
First, find the difference between the current price and original price.
$4015 - $2852 = $1163
Second, divide the price difference by the current price to get the percentage.
1163/2852 = .40778
Check the math by multiplying the original price by the markup percentage and add the original price to it.
$2852 X .40778 + $2852 = $4015
.8
All percents are out of 100, so to figure out the answer you must make the denominator, or bottom number in your fraction, 100.
To get to 100, you would multiply 5x20, because that equals 100. Because you multiplied the denominator, which is 5, you must multiply the top number by 20 as well.
4x20 = 80
So therefore, the answer is 80/100, so .8
