Here is the explanation.<br /> <br />Pedro’s bill if he uses Manana Water company:<br /><br />There is no standing charge to be paid, and no discount is given.<br /><br />He uses 700 m3 of water @€0.06 per m3 <br />So the total bill for 3 months = €0.06 x 700 = €42.00<br /><br />There are 4 quarters (1 quarter = 3 months) in a year.<br />So his total bill for 1 year = €42.00 x 4 <br /> = €168.00.<br /><br />Pedro’s bill if he uses Channel Water company:<br /><br />There is a standing charge of €30 every 3 months.<br /><br />He uses 700 m3 of water @€0.02 per m3 . <br />So the cost of the water used for 3 months = €0.02 x 700 = €14.00. <br /><br />So the total bill for 3 months = €30 + €14.00 = €44.00<br /><br />But he gets 20% discount off the first bill = 20% of €44.00 = €8.80 <br /><br />So the bill for the first quarter of the year = €44.00 - €8.80 = €35.20 <br /><br />For the rest of the year there are no discounts, so he pays €44.00 for the remaining 3 quarters.<br /><br />So his total bill for 1 year = (€44.00 × 3) + €35.20<br /> = €167.20<br />Ishaanhttps://www.blogger.com/profile/18219354842858941782noreply@blogger.com
