$.1d$

#### Work Step by Step

We know that one dime is equal to .1 dollars. Therefore, we know that the expression $.1d$ tells us the amount of money (in dollars) that $d$ dimes represents. For example, if we have $d=60$ dimes, the expression tells us that we will have $.1\times d=.1\times60=6$ dollars.
