Movie Tickets

Dear Dr. Data,

My two brothers and I want to go see a movie, the tickets are $5.75 per person an we also want to purchase candy for $2.25 and a drink for $3.50. How much money will we have left out of a $50 dollar bill? How much would we have left if we went to the evening show which is $2.50 more per ticket?

Prosperity student,
We added the three tickets and we got $17.25. Then we added the candy up and got $6.75. Then we added up the drinks and $10.50. Next we added all of it up and got $34.50, finally we subtracted that amount from $50. Our answer is $15.50. If you would go to the evening show, you would send another $7.50. If you subtract that from $15.50 you will have $8 left.

Salsa question

Anonymous said...

We packed 72 containers with tomato mix. Each salsa kit requires 2 containers of tomato mix. How many kits can we make?

If each kit sells for $4.00, how much money will we bring in with this batch of salsa?

The cost to grow each kit is $2.75. What profit will we make on our salsa?

Dear Mrs. Baxtor's class,

We would like to recommend Google Forms for your survey creation and data collection. This is an easy way to post questions and then give your community members a URL where they can go to answer them! Here are some step-by-step instructions: http://docs.google.com/support/bin/answer.py?hl=en&answer=87809 for creating a form/survey. Also, here is a sample form that we created: http://spreadsheets.google.com/viewform?formkey=dGxGamxCZjkyU3FXT19GVFJtU2FuRnc6MQ The answers come in on an Excel spreadsheet, here is what our data looks like from teachers in our school who took our sample survey: http://spreadsheets.google.com/ccc?key=0AsObDbgsk5DidGxGamxCZjkyU3FXT19GVFJtU2FuRnc&hl=en#gid=0 You can use Google Forms to quickly analyze the data with their graphs OR you can use another fun site called Create-a-Graph http://nces.ed.gov/nceskids/createAgraph/default.aspx to make some fancier graphs. Like the sample above that we created using our data:
