Agroup of 72 people travel to the beach for a clean-up day. some of the people bring their own supplies (such as gloves, water, and garbage bags). supplies are provided for the rest of the people. write an equation for the number of people for whom supplies will be provided, p, of b people bring their own supplies. math

P=72-B

Explanation:

The situation says that there is a group of 72 people from which some bring their own supplies, b, and for the rest the supplies will be provided, p. So, this means that:

P+B= 72

The situation is asking for an equation to determine the number of people for whom supplies will be provided, p. This means that you will have to isolate p from the equation:

P= 72-B
