Write an expression to represent this situation. (Let x represent the number of miles)
$75+1.45d

Explain your answer.

Answer 1

The expression represents the total cost of a dog training session with Terrell, which includes the fixed fee of $75 plus the variable cost of $1.45 per mile driven to and from the session (represented by "d" in the expression). To find the total cost for any given training session, one would substitute the number of miles driven (represented by "x") into the expression and simplify.
