Given:
One-time cleaning fee = $45
Per day rental charge = $23
Final bill = $229
To find:
The number of days for which John takes video camera on rent.
Solution:
Let the number of days be d.
Rental charge for one day = $23
Rental charge for d days = $23d
Total charges = One-time cleaning fee + Rental charge for d days
[tex]Total=45+23d[/tex]
Final bill is $229. So,
[tex]45+23d=229[/tex]
Subtract 45 from both sides.
[tex]45+23d-45=229-45[/tex]
[tex]23d=184[/tex]
Divide both sides by 23.
[tex]d=\dfrac{184}{23}[/tex]
[tex]d=8[/tex]
Therefore, the required number of days is 8.
