A group of friends were working on a student film. They spent all their budget on

The total budget for their student film was $720.

Step-by-step explanation:

From the information given, you know that they spent all their budget on costumes and equipment and that they spent 45% of the total budget on equipment. From this, you could inferred that in order to find the percentage they spent on costumes you have to subtract 45% from 100% that would indicate the total amount spent:

100%-45%=55%

According to this, you know that they spent 55% of the total budget on costumes and the statement says that the amount was $396. With this information, you can use a rule of three to find the amount that represents 100%:

396 →  55%

 x    ← 100%

x=(396*100)/55=720

The answer is that the total budget for their student film was $720.
