Answer 1

The cost of filling the gas tank is Rs. 800

15% decrease,= 1-(15/100)= 0.85

New cost = 0.85 * 800 = Rs. 680

The number of customers increases by 30%, which means that there will be 100% + 30% = 130% of the initial number of customers.

New income = Rs. 680 * 130% = 680 * 1.3 = Rs. 884

Revenue Change Percentage = [(New Revenue - Initial Revenue) / Initial Revenue] * 100

% change in revenue = [(884 - 800) / 800] * 100 = 10.5%

revenues increased +10.5%.
