Can someone me understand this question?
part a: virginia earned $14 walking her neighbors' dogs on saturday. she earned some extra money on sunday doing the same thing. write an expression with a variable that shows the total amount of money virginia earned saturday and sunday.
part b: virginia was able to walk 2 less than twice as many dogs as her friend alicia. write an algebraic expression to represent the number of dogs virginia walked compared with alicia.

Hey there! 

For Part A, because the amount earned on Sunday isn't specified, we can call this additional income x. Because we're writing an expression, we don't need an equal sign. The expression will be (x + 14). 

For Part B, "2 less than" will mean "– 2" and "twice than" will mean the amount of dogs that Alicia walked times 2. We can call the amount that Alicia walked y to avoid confusion with the last expression (though you could use whatever variable here) and your expression will be (2y – 2). 

Hope this helped you out! :-)
