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

Perfect!

ReplyDeletePedro’s bill if he uses Manana Water company:

There is no standing charge to be paid, and no discount is given.

He uses 700 m3 of water @€0.06 per m3

So the total bill for 3 months = €0.06 x 700 = €42.00

There are 4 quarters (1 quarter = 3 months) in a year.

So his total bill for 1 year = €42.00 x 4

= €168.00.

Pedro’s bill if he uses Channel Water company:

There is a standing charge of €30 every 3 months.

He uses 700 m3 of water @€0.02 per m3 .

So the cost of the water used for 3 months = €0.02 x 700 = €14.00.

So the total bill for 3 months = €30 + €14.00 = €44.00

But he gets 20% discount off the first bill = 20% of €44.00 = €8.80

So the bill for the first quarter of the year = €44.00 - €8.80 = €35.20

For the rest of the year there are no discounts, so he pays €44.00 for the remaining 3 quarters.

So his total bill for 1 year = (€44.00 × 3) + €35.20

= €167.20

Perfect!
