3. (5.7.12) On June 2, 2010 USA Today reported a story from Bloomberg News that said that the total price
tag for the project to build the new F-35 Joint Strike Fighter would be 65% higher than the original $232 billion
estimate. The cost now is estimated to be $382 billion.
The total cost of each plane would be $112.4 million, up 81% from the original $62 million. The cost to
produce each plane would be $92.4 million, about 85% higher than the original estimate of $50 million.
a. Check the arithmetic to see that the three percentage increases reported are correct.
b. Can you explain how the project cost can have increased by just 65% when the overall total per
plane increased by 81% and the construction cost alone increased by almost 85%?
4. (5.7.3) Check that your own GPA from last semester has been computed correctly using the rules in effect at
YSU. If you are in your first semester and don't yet have a GPA, imagine the grades you expect at the end of
this semester and figure…

- People who live in Cape Carmel major reasons for their worry is that there are many homes built at, or nearly at, sea level along the coast of Cape Carmel. The total value of these homes is more than 100 million dollars. Ice melting increases the sea level. Global sea level is measured relative to the sea level in the year 1870. If the sea level in 1870 is represented by 0 inches, then Cape Carmel sea level has risen from 1 6.8 inches to 8.4 inches in the years from 1992 to 2012. If the sea level rises to 24 inches, it will have devastating effects on the homes along the coast of Cape Carmel. Many of the Cape Carmel residents want to know if, and when, they should sell their property before it is washed away into the sea. You must help residents understand more about the rising sea level in Cape Carmel to help them predict when they should sell their homes. 1. To write any formula, you need to define your variables. Do that first. Be clear and complete in your definitions.
