Answer:
25
Step-by-step explanation:
it's so easy to get to know
So he has to sell it at 19.5+2=21.5 dollars
so assume19.5=100%
the markup is 2 dollars
2=x%
find x if 19.5=100%
so since they are proportionite
19.5:100 and 2:x
if we make them fractions and flip one of them then multiply we will get 1 since
2/4=1/2
2/4 times 2/1=4/4=1 so
19.5/100 times x/2=19.5x/200=1
19.5x/200=1
multiply both sides by 200
19.5x=200
divide both sdies by 19.5
x=10.256 aprox
x=10.3% markup
We have been given a Quadratic equation, where we have to find the real values of x ~
So, let's proceed with middle term splitting method :
Now, we have two conditions here~
Either (x + 6) = 0
or (x - 1) = 0
2000 nearest thousand
2160 nearest ten
2200 nearest hundred
