Answer:
The number of units of good G that can be purchased if all income is used to purchase good G is 15 units.
Explanation:
Since D is on the y-axis, indicating G is on the x-axis, the formula for calculating the marginal rate of transformation (MRT) is given as follows:
MRT = - PG / PD …………………. (1)
Where:
MRT = Marginal rate of transformation = -2
PG = Price of good G = ?
PD = Price of good D = $6
Substituting the relevant values into equation (1) and solve for PG, we have:
-2 = - PG / $6
PG = -2 * (-6) = $12
Therefore, we have:
Number units of good G if all income is spent on it = Monthly income / PG = $180 / $12 = 15
Therefore, the number of units of good G that can be purchased if all income is used to purchase good G is 15 units.
