Answer:
D. a 2 percent decrease in quantity demanded.
Explanation:
We must remember that Price elasticity is calculate as follows:
↓Q / ΔP
If Ep = 0.2 and ΔP = 10% = 10/100 = 0.10
Then:
↓Q/0.10 = 0.2
↓Q = 0.2 x 0.10 = 0.02 = 2%
The customer demand is quite inelastic thus, aren't quite price sensitive to move to other goods.
