### Education Costs Must Include Gas Expenses

In 1963 Bob Dylan sang "the times they are a-changin'." He was correct then and his words are still true today. In the 21st century Dylan would probably sing "the times are forever changin'."

On 23 February 2003, I wrote GDT::Speaks:: I Say No to MCCCD Tuition Increases. The note contained the following list itemizing the cost for taking a 3-credit computer class at SCC.

```   tuition ............ \$153  [3-credit course @ \$51 per credit]
registration fee ... \$  5
computer lab fee ... \$  9
book ............... \$ 50
gas* ............... \$ 53
-------------------------
total .............. \$270

* Gas expenses were computed using a vehicle that gets
20 miles to the gallon; 22 miles round-trip to/from
campus;  32 round-trips to/from campus; and a gas
price of approximately \$1.50 per gallon.
```

On 8 March 2003 (13 days after I wrote about tuition rates), gas was at `\$1.85 per gallon`. Using `\$1.85` instead of `\$1.50` caused the cost of a 3-credit computer course to increase `4.4%` to `\$282`.

Fast forward to 5 April 2005...

Tuition rates have increased from `\$51 per credit hour` to `\$60 per credit hour` and the price of gas in the Valley of the Sun approximates `\$2.23 per gallon`.

##### Exercises

1. Update the following table using the increased tuition rate and gas price.

```   tuition ............ \$???  [3-credit course @ \$60 per credit]
registration fee ... \$  5
computer lab fee ... \$  9
book ............... \$ 50
gas* ............... \$ ??
-------------------------
total .............. \$???
```
2. Calculate the percentage increase in the cost of education from spring 2003 to spring 2005.

##### Update::16 January 2006

Gas prices are virtually unchanged from 5 April 2005. The issue of tuition rates will be re-visited during the Spring 2006 semester.
