Math for Journalist

A local college releases figures showing that its total budget is $120 million. Of that total, $80 million comes from the state, $6 million from student tuition, and the remaining $34 million from fees, grants and gifts.
* Figure the percentage of the college’s budget that comes from each source –
· 67 percent comes from the state
· 5 percent from student tuition
· 28 percent is from fees, grants and gifts.
* Identify the significance of each funding source (the most vs. the least, etc.) –
· The most funding comes from the state
* Using plain words, instead of numbers, explain the proportion of funding that comes from different sources. Say it in the way you think would make it most easily understood –
· Most of college’s funding is given by state, while the rest is supplied from fees, grants, and gifts, as well as from tuition.
2) Your editor assigns you to do a story about prison sentences handed down in cases of aggravated assault. He gives you the following figures from an anti-crime group that is lobbying for tougher sentencing guidelines. The cases represent the people convicted for aggravated assault in San Jose in one month in 2006.
* Calculate the average prison term for people convicted of aggravated assault, taking care to convert some of the terms to figures that will compare properly (months vs. years) –
· The average prison term for people convicted of aggravated assault for 22 months.
* Calculate the median prison term for people convicted of aggravated assault –
· The median prison term for convicted of aggravated assault is for one year.
* Explain why the average or median figure is the most accurate description of prison terms – The median is the simplest way to show information.
3) The state legislature is considering exempting restaurant food sales from the sales tax in the same way grocery sales are exempt.
* First, find out the state sales tax –
· California state tax is 8.25%
* Then determine and explain how much fast-food patrons who pay $5 per meal would save in a year if they eat out once a week –
· Every meal would cost $5 to $4.59 (8.25% off of $5), for a difference of 41 cents per meal. The prices decrease by 41 cents over 52 weeks which would allow you to save about $21.32 every year.
· Explain how much people would save if they spend $20 per meal once a week for a year – After calculations people would save $85.80 a year.

  1. 1) You've got the numbers right, but you need to be more specific in your explanatory sentence. So say something like "about two-thirds of the college's funding comes from the state," etc. ("Two-thirds" is easier to visualize than 67 percent, and more informative than "largest amount.")

    2) I didn't ask which one is the simplest ... I want to know which one is the most accurate, and why.

    3) OK
