You are given two variables, already defined, named total_weight, containing the weight of a shipment, and weight_of_box, containing the weight of the box in which a product is shipped. Write an expression that calculates the net weight of the product.

given the options, i would say your best bet is c. the modem supports up to 56 kbps, which is too low for video streaming. dial up modems use actual phone lines, which only can go up to 56 kbps as that's more than sufficient for traditional phone calls. this is also the reason why when a dial-up modem connects, you hear all those sounds. it's literally using the phone line to establish a connection.
