Pham is saving money to buy new headphones. The headphones cost $200, but she has saved only 45% so far. How much more does Pham need to save to buy the headphones? please help giving brainlest it’s due in a few minutes (i have to show work so if you can please send an example)
cmon y’all..:(

she needs $110

Step-by-step explanation:

Just multiply 200 by 0.45 to get 90 then subtract 90 from 200

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.
