Question
100%
Getting going in the morning was
probably hard for folks on the Overland
Trail (just as it may be for you today), so
coffee was a highly valued commodity.
The Cazneau family starts their journey
with a supply of 30 pounds of coffee.
When they arrive at Sutter's Fort in
California, 188 days later, they have only
3 pounds left.
1.
Draw a graph showing the amount of coffee remaining as a function of the time elapsed since the start
of the journey. For simplicity, assume the Cazneaus consume coffee at a constant rate.
2.
Find the average amount of coffee consumed per day.
3.
Develop an equation for the function represented by your graph.
Find the slope of your graph.
4.
5. Suppose that at the beginning of their 188-day journey, the Cazneaus are 1600 miles from Sutter's Fort.
a. How many miles per day do they travel? For simplicity, assume they travel the same distance
each day.
b. Of course, as the Cazneaus travel, their distance from Sutter's Fort decreases. Write a formula
expressing the distance remaining as a function of the number of days they have been traveling.
4kgrar of your function from part b.
