Traveling In Canada Part 2

After spending a week with our friends, it was time to head back to the US. Before we left, we had to get some gas for the car. We picked the best price in town, and filled up the tank.

The best price we found was 98.6¢ for one liter. That is in Canadian dollars (or cents to be exact). After we crossed the border and got lost for a while due to inaccurate directions, it was time to fill up the tank again, in the state of New York. The best price we could find was $3.37 for a gallon. That is US dollars.

Your job is to figure out whether gas was cheaper in Canada or in the US?
Here is some additional information to help you:
$1.00 CAN = $ .80 US
1 gallon = 3.8 liters

My dad's computer credit card problem

My dad got me and my sister a Widows Vista because our old one had a virus. The virus deleted all the memory & documents. It ruined the screen, printer, mouse, and keyboard. We bought Windows Vista, and it had everything except the printer. Vista came at a price of $799.99 without taxes. The printer was $149.99 without the taxes.

Your job is to:
1. find out the taxes (8.25% of the total price) and
2. figure out how much money my dad has to pay per month so he can finish paying in 18 months.

Rainfall

Lately there have been a lot of talk about Hurricanes wrecking the coastal regions of the US. The latest one on the news is Hurricane Ike. One statistic that I heard about this hurricane was that here in Los Angeles we have had 0.16 inches of rainfall from March 2008 to September 2008, while Hurricane Ike produced 15.75 inches of rain in just a few days in Houston, Texas.

Below are the graphs that show the average precipitation for the two cities from The Weather Channel Click on the image to enlarge it and see the numbers clearer.
Your job is to answer the following questions:

1. About how many years of average Los Angeles precipitation would equal the rainfall produced by Ike in Houston?
2. About how many months of average Houston precipitation would equal the rainfall produced by Ike?

Remember to explain how you found the answers to the questions.

Rosario's Dilemma

The following problem was submitted by Rosario.

Today my dad bought a box of chocolates. It contained 48 pieces. If they shared the 48 pieces equally, each of my household members (not including me) would have gotten 9.6 bars. But I want some too. :)

I need your help to figure out exactly how many bars each person should get. And how many people there are in total.

Sunday Times

Mr. Billett and I have the Sunday edition of the LA Times delivered to our door. We recently got a bill, and Mr. Billett sat down to figure out whether we are saving money by having the paper delivered, or whether it would be better to walk down to the corner and pick one up in person every Sunday.

According to the bill, we paid $17.20 to have the paper delivered every Sunday between 03/10/08 and 05/05/08. The price of the Sunday Times is $1.25 if you buy it in person.

Your job is to figure out:
1. Which is the better deal: delivery or walking to get the paper?
2. How much would we save over a whole year with the better deal?
