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 of gas?
55,000 / 200 = 275
(275 * 0.6) + 13.75 = ?
x/3 + 4 = 7
To find out how much the man pays when he uses 55,000 m3 of gas, we can follow these steps:
Step 1: Calculate the variable cost
The man pays 60 cents for every 200 m3 of gas used. So, we need to determine how many units of 200 m3 are there in 55,000 m3.
Number of 200 m3 units = 55,000 m3 / 200 m3 = 275 units
Now, multiply the number of units by the cost per unit:
Variable cost = 275 units * $0.60/unit = $165
Step 2: Add the fixed charge
The man pays a fixed charge of $13.75, which is unrelated to the volume of gas used.
Step 3: Calculate the total cost
To find the total cost, add the variable cost and the fixed charge:
Total cost = Variable cost + Fixed charge
Total cost = $165 + $13.75
Total cost = $178.75
Therefore, the man pays $178.75 when he uses 55,000 m3 of gas.
