Melissa will participate in a charity walkathon. Her mother will donate $10 for Melissais
participation plus an additional $2 for each mile that Melissa walks.
a) If Melissa walks 15 miles, what will be the amount of her mother's donation?

Let x represent number of miles.

We have been given that Melissa's mother will donate $2 for each mile that Melissa walks. So amount donated by Melissa's mother for x miles would be .

We are also told that her will donate $10 for Melissa's participation. The total amount of money donated by Melissa's mother will be participation amount plus amount donated for x miles.

.
