Answer and explanation:
Saving implies setting an amount of money of your income aside and put it into a bank account or store it somewhere considered safe. If deposited in a bank the money gains interest, thus, there will be a relative increase in the initial sum deposited.
Investing implies providing money to a third party or using that money personally to start up a venture. In such cases, there is a risk that the investment could be lost.
