In total, you have $668.00.
To reserve enough for the last day, you need to subtract the last day's budget:
[tex]668.00-85.00=583.00[/tex]
This means that, for the remaining 6 days in the week, you have $583.00.
Assuming an equal amount is being spent each day, you can calculate the daily budget by dividing the remaining total by the number of days left.
[tex] \frac{583}{6} =97.16[/tex]
To avoid going over budget, you can spend $97.16 per day for the other six days.
Hope this helps!
