amount

The amount of money each member of a band earns playing at a
graduation party varies inversely as the number of members in the band.
If the band has five members, each member earns $70. Write an
equation that models the relationship between the number of members
in a band, n, and the amount each member earns, d.
Use the equation to calculate the amount each member earns if there
are four members in the band.

$\displaystyle d = \frac{k}{n}$ , where $\displaystyle k$ is the constant of proportionality

sub in the given values and solve for $\displaystyle k$ , then determine $\displaystyle d$ if $\displaystyle n = 4$
