Understanding the Problem

In this problem, we are given the price of loose tea in grams and asked to find the cost of a specific quantity of tea in pounds. To solve this problem, we need to convert the given quantity from pounds to grams and then multiply it by the price per gram.

Converting Pounds to Grams

First, let's recall that 1 pound is equivalent to 453.592 grams. We can use this conversion factor to convert 0.4 pounds to grams.

# Define the conversion factor pounds_to_grams = 453.592 quantity_pounds = 0.4

quantity_grams = quantity_pounds * pounds_to_grams

Calculating the Cost

Now that we have the quantity in grams, we can multiply it by the price per gram to find the total cost.

# Define the price per gram price_per_gram = 0.71

total_cost = quantity_grams * price_per_gram

Rounding the Answer

Since we are dealing with money, we need to round the answer to two decimal places.

# Round the answer to two decimal places
total_cost = round(total_cost, 2)

The Final Answer

Now that we have calculated the total cost, we can compare it to the given options to find the best answer.

# Define the given options
options = [108.70, 144.93, 536.77, 715.69]
closest_option = min(options, key=lambda x:abs(x-total_cost))
print("The final answer is $", closest_option)

Conclusion

In this problem, we used mathematical concepts to convert pounds to grams and calculate the total cost of a specific quantity of tea. We also rounded the answer to two decimal places to ensure accuracy. The final answer is $144.93.
