The number that represents the change in the number of plates the restaurant has is; -56
We are told that;
8 plates are accidentally broken everyday
Period of breaking of plates = 1 week = 7 days
Now, if 8 plates break everyday for 7 days, then;
Total number of plates broken for 7 days = 8*7 = 56 plates
Now, since this is a reduction in amount of plates and not an increase, the right notation will be negative and so the correct representation of the change in number of plates for the week is -56.
