A 16-cup carton of milk costs $7.68. What is the price per quart?

The price per quart is $1.92.

Step-by-step explanation:

A quart is 4 cups.  Since 16 is divisible by 4, you should divide 4 from 7.68 in which you should get $1.92 as your answer.

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.
