Astore is selling a black pair of shoes for $79.45 and a brown pair of shoes for $133.99. the black pair of shoes is marked up by 44%, and the brown pair of shoes is marked down by 21%. which pair of shoes is more expensive, and how much more expensive is it? round all dollar values to the nearest cent. a. the black pair costs $6.82 more than the brown pair. b. the black pair costs $8.56 more than the brown pair. c. the brown pair costs $9.72 more than the black pair. d. the brown pair costs $12.54 more than the black pair. select the best answer from the choices provided a b c d

The answer is B

Step-by-step explanation:

In the case of Black pair of shoes, we have that is marked up by 44% so the final price is:

79.45 + 0.44x79.45 = 114.41

And in the case of Brown pair of shoes, we have that is marked down by 21% so the final price is:

133.99 - 0.21x133.99 = 105.85

So at the end the Black pair of shoes is more expensive than the Brown pair of shoes

114.41 - 105.85 = 8.56

step-by-step explanation:

stew:

we need to find the slope

m = (y2-y1)/ (x2-x1)

    = (2650-795)/(10-3)

    = 1855/7

connie:

we need to find the slope

m = (y2-y1)/ (x2-x1)

we have two points (0,0) and (4,800)

m = (800-0)/(4-0)

  m = 800/4

felicia:

260 words per minute

200< 260 < 265

connie < felicia < stew

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
