Answer:
3 and 46.67 units
Explanation:

The price of good B is
= {The price of good Z (Pz)} ÷ {Marginal rate of transformation}
= {$6} ÷ {2}
= 3
Now the number of units to be purchased for all income used is
= (Monthly income spent on two goods) ÷ (price of good B)
= ($140) ÷ (3)
= 46.67 units
By applying the above formula we can find out the price of good B and the number of units purchased
