THE WATER BILL

Process:

·       In subparagraph a) we take the fixed part of the table and add it with the variable part, that part is multiplied by 0 because we don´t consume water and multiply it by VAT which is 10%. We do this same process in all, but the distribution part that according to what we have spent we have to choose between three different blocks and in garbage collection since we 
don´t have to increase the VAT.

 

·       In subparagraph b) we take the fixed part of the table and add it with the variable part, that part is multiplied by 23 because the water consumption is 23m³ and multiply it by the VAT which is 10%. We do this same process in all but, the distribution part that as we have spent 23m³ we have to choose block 1 multiplied by the said cubic meters and in the garbage collection since we don´t have to increase the VAT.

 

 

·       In subparagraph c) we take the fixed part of the table and add it with the variable part, that part is multiplied by 40 because the water consumption is 40m³ and multiply it by the VAT which is 10%. We do this same process in all but, the distribution part that as we have spent 40m³ we have to choose block 1 and 2, in this case we have to start the 40 meters in two blocks, that is, 35 in block 1 and 5 in block 2, add and multiply by VAT and in garbage collection since we don´t have to increase the VAT.

 

·       In subparagraph d) we take the fixed part of the table and add it with the variable part, that part is multiplied by 53 because the water consumption is 53 m³ and multiply it by the VAT which is 10%.      
We do this same process in all but, the distribution part that as we have spent 53 m³ we have to choose block 1 and 2, in this case we have to start the 53 meters in three blocks, that is, 35 in block 1, 15 in block 2 and 3 in block 3, add and multiply by VAT and in garbage collection since we don´t have to increase the VAT. 

 

·       In subparagraph e) we have to take out which block of the distribution are the €59, 94, we know that it is in block 1. We removed the variable part with VAT (29, 04) which are 30, 9. 30, 9 we divide it by VAT (1, 1) which is
 28, 09 without VAT. We take out what is the variable part to know the result of 1 m³ which is 0, 9365. The VAT-free part (28, 09) is divided by the result of 1 m³ (0, 9365) which result are 30 m³ consumed.
