With this! jen is deciding to get a new phone. one deal is a free phone with a two year contract, but she will have to pay the sales tax of 8% on the original price of $399 and the monthly charge is $10 more than she currently pays. the other is on sale for $199, plus 8% sales tax. the monthly charge is the same as what she currently pays. over the two year contract period, which phone will be the lower cost and by how much?

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.

answer: you need the equation in the question so i can answer it
