I can help with this. He doesn't tell how many dollars she earned from her dad but tells you what is left. So we add 13.73 + 1.77
We add because She used to spend it and because she only gave us what was left. We want to push it to what it was before so we do the opposite.
13.73 + 1.77 = 15.5
I am not really sure of what the words are on the last part but i think u can figure it out. My answer is 15.5 but if you aren't asking for this just ignore it.
