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?
Answered by Reiny
charge = .86x + 4.49

if charge = 69.85

69.85 = .86x+4.49
.86x = 65.36
x = 76
Answered by Ms. Sue
69.85 - 4.49 = 65.36

65.36 / 0.86 = 76 cubic meters
