I attended a workshop in Casa Grande Az from 23-27 June. I drove to the workshop from superior to Casa Grande chamber of commerce. Estimate the cost on my transportation for attending the workshop. 1. Explain the strategies you used 2. Give the resources you used to estimate. 3. What information did you need/collect to estimate the solution to the problem.

OpenStudy (dumbcow):

hey i live in AZ

OpenStudy (anonymous):

doesnt answer my question!

OpenStudy (dumbcow):

you need to know distance traveled, price of gas, estimated car mpg

OpenStudy (anonymous):

Im really dumb! and i dont know any of tht..

OpenStudy (dumbcow):

imagine you really had to drive from superior to casa grande, how much would it cost to drive there and back? no different than figuring out how much it costs to drive to work or school each day

OpenStudy (anonymous):

Well I think you can drive 25mi in 1 gallon?

OpenStudy (dumbcow):

thats a good estimate for most cars these days now what is price of gas right now?

OpenStudy (anonymous):

The price of Gas here in Superior is $3.39

OpenStudy (dumbcow):

ok good, now how far do you have to drive? use a map

OpenStudy (anonymous):

63 miles

OpenStudy (dumbcow):

are you doing round trip?

OpenStudy (anonymous):

Im doing superior to casa grande is 63 miles

OpenStudy (dumbcow):

well anyway, you would just double the cost Find number gallons used by taking miles divided by mpg --> g = 63/25 Then multiply by price of gas --> cost = 3.39*(63/25)

OpenStudy (anonymous):

8.5428?

OpenStudy (dumbcow):

yep

OpenStudy (dumbcow):

For trip, the formula is: cost = priceGas * (miles/mpg)

OpenStudy (anonymous):

3.051?

OpenStudy (dumbcow):

?? no, 8.54 was correct

OpenStudy (anonymous):

Oh okay i get it now thanks! You were a big help! :D
