Monica wants to travel to California over spring break. Her mom said she would double the amount she is able to save during the school year to help her pay for the $1,850 plane ticket. Monica currently has $560 in her savings account. Which inequality best represents the least amount of money she would need to contribute to cover the cost of the plane ticket?

1.4

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3
