Answer:
To estimate the earnings for the week, we first need to find the total weight of coffee beans collected over the week. Then, we can multiply the total weight by the rate per kilogram to get the estimated earnings.
Total weight of coffee beans collected over the week:
13.3kg + 10.9kg + 15.7kg + 14.4kg + 12.9kg = 67.2kg
Now, we can calculate the estimated earnings for the week:
Earnings = Total weight times Rate per kilogram
Earnings = 67.2kg times K5.80/kg = K389.76
The estimated earnings for the week are K389.76.
