## Step 1<br />The problem is asking about the behavior of prices when the demand and supply of a product increase. <br /><br />## Step 2<br />In economics, the price of a product is determined by the interaction of supply and demand. <br /><br />## Step 3<br />When both demand and supply increase, the price typically rises. This is because the increase in demand indicates that more consumers are willing to buy the product, which can drive up the price. <br /><br />## Step 4<br />Simultaneously, the increase in supply indicates that more of the product is available, which can also drive up the price. <br /><br />## Step 5<br />Therefore, when both demand and supply increase, the price generally rises.
