The charges on a monthly water bill came to $0.86 per cubic meter of water used, plus a service charge of $4.49.
Last month Jeremy's water bill came to $69.85, how many cubic meters of water had he used?
charge = .86x + 4.49
if charge = 69.85
69.85 = .86x+4.49
.86x = 65.36
x = 76
69.85 - 4.49 = 65.36
65.36 / 0.86 = 76 cubic meters
To find out how many cubic meters of water Jeremy had used, we need to subtract the service charge from his total bill, and then divide the remaining amount by the cost per cubic meter.
Let's calculate step-by-step:
1. Subtract the service charge from the total bill:
Total bill - Service charge = $69.85 - $4.49 = $65.36
2. Divide the remaining amount by the cost per cubic meter:
$65.36 ÷ $0.86 per cubic meter = 76 cubic meters
Therefore, Jeremy had used 76 cubic meters of water last month.
To determine how many cubic meters of water Jeremy had used, we need to set up an equation based on the given information.
Let's assume the number of cubic meters of water used by Jeremy is represented by "x".
According to the given information, Jeremy's water bill consists of two parts:
1. A charge of $0.86 per cubic meter of water used.
2. A service charge of $4.49.
The total amount of Jeremy's water bill is $69.85.
So, we can write the equation as:
$0.86x + $4.49 = $69.85
To solve for "x," we need to isolate the variable on one side of the equation.
Subtracting $4.49 from both sides, we have:
$0.86x = $69.85 - $4.49
$0.86x = $65.36
Now, we divide both sides of the equation by $0.86 to solve for "x":
x = $65.36 / $0.86
Calculating this, we find:
x ≈ 76
Therefore, Jeremy had used approximately 76 cubic meters of water.
