Think of three example from your own experience, and explain how they demonstrate the concept of diminishing marginal utility.

Examples:

1.) Having a stain on your rug there's only so much you can get out before your damaging your rug with cleaner

2.) Babysitting and having the child miss there mom, there's only so much you can do to try to calm him/her down

3.) Watering plants, if you haven't watered plant in a long time so you give them extra water, if you keep giving the plant extra water it will eventually drown and die.
