------------------------
write the function that models the inverse variation.
y = k/x ---- k = some constant
11 = k/7 ---> k = 77
=========================
find y when x=10
y = 77/10
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
It's not necessary to solve for k, but it's easy.

suppose that x and y vary inversely,
x =
and x=7 when y=11.
7 =
11*7 = k
k = 77
write the function that models the inverse variation.
x =
then find y when x=10
10 =
10y = 77
y =
y = 7.7
