Final answer:
The amount of money available for the equipment is $25,000.
Step-by-step explanation:
To calculate the amount of money that will be available for the equipment, we need to find 50% of the supply monies. Since the investigator has permission to rebudget $50,000, we can calculate this by multiplying $50,000 by 0.50. The result is $25,000. Therefore, $25,000 will be available for the equipment.
