Answer:
The DJ can play at the dance for 6 Hours
Explanation:
1. Add the decorations and food plus the additional fee of $12
$175+ $125= $300
2. Subtract the budget and the total so far
750-300= 450
3. Get the amount owed per hour to DJ and divide by the new budget
450/75= 6
The DJ can play at the dance for 6 hours
Have a good day!
