Can someone please help me please? This is so confusing. 9. The function M(d) below
relates the distance (measured in miles) Bob can
drive his rental car and the amount of money (in dollars) it will cost.

It takes as input the number of dollars spent and returns as output the number of miles driven.

M(d)=40(d-35)

Write the equation that represents the
inverse function D(m), which takes the number of miles driven as input and returns the number of dollars
owed.
