Emily sold 140 boxes of cookies for a fundraiser. If she sold 80% of the total number of boxes sold for the fundraiser, how many total boxes of cookies were sold for the fundraiser?

175

Step-by-step explanation:

140 is 80% of 175

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.

assuming you mean addition: addition and subtraction are reverse operations.
