Final answer:
To find the number of paintball guns rented, subtract the flat fee for the field from the total cost and divide the remaining amount by the cost per gun. In this case, 7 paintball guns were rented.
Step-by-step explanation:
To find the number of paintball guns rented, we need to subtract the flat fee for the field from the total cost and then divide the remaining amount by the cost per gun. To find the number of paintball guns rented, subtract the flat fee for the field from the total cost and divide the remaining amount by the cost per gun. In this case, 7 paintball guns were rented.
Total cost - Flat fee = $176 - $36 = $140
Number of paintball guns rented = Total cost / Cost per gun = $140 / $20 = 7
Therefore, 7 paintball guns were rented.
