Question

The Cazneau family starts their journey with a supply of 30 lbs of coffee. When they arrive at Sutter's fort in California, 188 days later, they have only 3 lbs left. Find the average amount of coffee consumed per day. Please explain your process in finding the answer.

Answer 1

Answer:

The average amount of coffee consumed per day was 0.14 lb

Step-by-step explanation:

we know that

To find out the average amount of coffee consumed per day, divide the total amount of coffee consumed by the number of days

Let

x -----> the total amount of coffee consumed in pounds

y ----> the number of days

we have

To find out the total amount of coffee consumed subtract 3 lbs from 30 lbs

$x=30-3=27\ lbs$

$y=188\ days$

so

$\frac{27}{188}=0.14\frac{lbs}{day}$

therefore

The average amount of coffee consumed per day was 0.14 lb
