# . 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.
