When the quantity of SCUBA lessons demanded by Hawaiian tourist’s increases from 800 to 1,000 weekly and if the price drops/falls from $30 to $20 per session, by using the arc elasticity formula, the price elasticity of demand will be: (i) 5.555. (ii) 1.800. (iii) 0.556. (iv) 1.111. (v) 0.444.
Can someone help me in getting through this problem.
