Worked Solution & Example Answer:A water company charged the following in 2017 - OCR - GCSE Maths - Question 8 - 2018 - Paper 2
Step 1
Calculate the Total Water Charge
Answer
To calculate the total amount Jenny needs to pay for the water, we first determine the cost of the water used:
Number of cubic meters of water used: 110 m³ Cost per cubic meter: £2.00
Thus, the total water charge is calculated as follows:
[ ext{Total Water Charge} = 110 ext{ m}^3 \times £2.00 = £220 ]
Step 2
Step 3
Determine the Additional Amount Owed
Answer
Finally, we need to find out how much more money Jenny needs to pay to the water company. We add the fixed charge to the total water charge:
Fixed charge: £45 Total water charge: £220
Total amount owed:
[ ext{Total Amount Owed} = £220 + £45 = £265 ]
Now, we find the difference between the total amount owed and the amount already paid:
[ ext{Additional Amount Owed} = £265 - £240 = £25 ]
Thus, Jenny needs to pay an additional £25.
