Answer: $81.60
Step-by-step explanation:
When we have an original price OP, and a markup of X% (this is how much increases the price with respect to the original price)
The retail price will be:
RP = OP + (X%/100%)*OP
RP = OP*(1 + X%/100%)
In this case, we have:
Original price = OP = $68
markup = X% = 20%
Replacing these in the above equation, we get:
RP= $68*(1 + 20%/100%) = $68*(1 + 0.20)
RP = $68*(1.20) = $81.60
Then the retail price of this particular item is $81.60
Answer:
The answer is B
Step-by-step explanation:
y=5x+2, as the slope is 5x, and the y-intercept is 2
F(-6) = (-6)2 + 2(-6)
= -12 - 12
= -24
Simple!
Since we can observe that they all have the same denominators (bottom part) we can just observe the numerator (top part)
6 is indeed greater than 5, yes? So we can safely say that
6/8 > 5/8
Now the for the second part.
6 is smaller than 7, yes? So we can make the observation that
6/8 < 7/8
Hope that makes sense! (Be sure to thank me, plz)
P.S. If you want an example of unlike denominators, let me know. <span />
