Read the following scenario. imagine you are at the laundry mat and you see these directions. 1. use credit card or cash to purchase tokens. machines do not accept coins. 2. choose a washing machine. select water temperature, water level, and type of cycle (gentle, permanent press, or regular) before entering tokens. 3. once water is flowing, add detergent, then items to be washed. 4. the washing machine lid must be closed before the cycle will begin. 5. do not open washers until the blue light goes off at the end of the cycle. according to those directions, which of the following is true? detergent should be added before the water begins to flow. tokens need to be entered before water level and other settings can be selected. when the blue light is illuminated, it is okay to open the washer. tokens are needed to operate the washing machines.

i would say the answer would be B.

The correct answer would be option D "Tokens are needed to operate the washing machines", this is the correct option because in the directions it is clearly stated in the first step, that you have to use credit card or cash to purchase tokens.  Option A is discarded because in step number 3, it clearly states to add the detergent once water is flowing. Option B is discarded because in step 2, it clearly states to select water temperature, water level and type of cycle before you enter the tokens. And finally, option C is discarded because in step 5, it clearly says that the blue light has to go off (be turned off) before you can open the washer.

idk i just need the points
