Final answer:
Manny will pay $132.54 for shipping and handling after calculating 20% of the original price of the washing machine, which is $662.70.
Step-by-step explanation:
To calculate the shipping and handling Manny will pay for the washing machine, we need to find 20% of the price of the machine ($662.70). To do this, we convert the percentage to a decimal (20% = 0.20) and then multiply by the price of the machine:
Shipping and Handling = 0.20 × $662.70 = $132.54
Therefore, Manny will pay $132.54 for shipping and handling, which corresponds to option a).
