Aprice of a phone is marked down from 350 to 287 for a sale. the following week the phone is marked down again but the same percent as during the week before. how much lower than the original price is the price after the second markdown?
a) 51.66
b) 114.66
c) 126
d) 235.34

D. 235.34

To answer this question we must first find the percentage of decrease.

To do this we must subtract 287 from 350

to find the difference. -63

Next, we must divide -63 by the original number, 350, to find -0.18.

Now we will multiply -0.18 by 100 to find the percentage.

So, the decrease is by -18%

Because -18% of 287 is 51.66 this will be the amount of money we subtract.

So, 287 - 51.66

235.34 is the price  after the second markdown.

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.
