+225 Can anyone help? There is a problem (the last one) on my homework that I don't completly understand. It's about something we didn't learn about in class. Once again, can anyone help?
Okay, here's the problem;
Serena received a gift card to download music from the internet. She downloaded 3 songs on Monday, 5 songs on Tuesday, and one half of what was left on Wednesday. She has 6 songs left. How many songs were initally on the gift card? Use the work backward strategy.
Wow, that was a lot of typing!
I don't need an exact answer, just a "how to" would be awesome. I am thinking that the answer is 21 songs to begin with, but I have no idea. A thank you in advance!
Llama On!

Say the card is good for a total of N songs
By the end of Tuesday's shopping there are N - 3 -5 songs left on the card.
On Wednesday, she downloads half of these, so we can say the Wednesday
shopping used up (N - 8)/2 more songs
So by the end of Wednesday's shopping, she has downloaded how many songs all told?
write your answer involving N and some numbers ....
that's a start .....
