Could also assume rounding down from 18.61, 18.62, 18.63 or 18.64.
Put the dang answer
To determine the possible range of the actual weight of Sam's dog, we need to consider the rounding process that was used. When rounding to the nearest tenth of a pound, any weight between 18.55 pounds and 18.65 pounds would round to 18.6 pounds. Thus, the possible range of the actual weight of Sam's dog would be between 18.55 pounds and 18.65 pounds.
