Arental car agency charges a flat fee of $110.00 plus $46.00 per day to rent a certain car. another agency charges a fee of $70.00 plus $54.00 per day to rent the same car.
using a graphing calculator, find the number of days for which the costs are the same. round your answer to the nearest whole day.

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.
