(ECO) Assume that the supply of good X is perfectly inelastic. If there is a decrease in demand, then the equilibrium quantity of marketable goods will Bbl6epute OAMH OTBeT: decrease but the equilibrium price remains unchanged stay the same and the price goes up rise and the price will fall remain unchanged but the price will decrease

## Step 1<br />In this problem, we are dealing with the concept of supply and demand in economics. The supply of good X is perfectly inelastic, which means that the quantity supplied does not change regardless of the price. This is represented by a vertical supply curve on a graph.<br /><br />## Step 2<br />The demand for good X is decreasing. This is represented by a shift to the left on the demand curve.<br /><br />## Step 3<br />When the demand curve shifts to the left, it intersects the supply curve at a lower point. This indicates that the equilibrium quantity of marketable goods will decrease.<br /><br />## Step 4<br />However, since the supply is perfectly inelastic, the price does not change. This is because the quantity supplied does not change regardless of the price.
