. A man pays 60 cents for every 200m3 of gas used, plus a fixed charge of $13.75.How much does he pay when he uses 55 000m3 gas?
13.75 + 55000(.60/200) = 178.75
55000m3 /200m3= 275m3
275m3*60 cent= 16500
16500/100=165.00
$165.00+$13.75= $178.75
13.75 + [0.6(55,000/200)] = ?
Can I see a working out please.
To calculate the total amount paid, we need to consider two components: the cost based on the gas used and the fixed charge.
1. Cost based on gas used:
The man pays 60 cents for every 200 m3 of gas used. Let's find out how many times 200 m3 goes into 55,000 m3.
55,000 m3 ÷ 200 m3 = 275 times
Since he pays 60 cents for every 200 m3:
275 times × 60 cents = $165
2. Fixed charge:
The man has to pay a fixed charge of $13.75, regardless of the amount of gas used.
Now, let's add the cost based on gas used and the fixed charge:
$165 (cost based on gas used) + $13.75 (fixed charge) = $178.75
Therefore, the man pays $178.75 when he uses 55,000 m3 of gas.
