A group of 727272 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, ppp, of bbb people bring their own supplies.

Answer 1

`b+p=72`

Or

`p=72-b`

Explanation:

We can represent this situation with an equation that shows that when b and p are added, then the total number of people will be 72

The number of people who bring supplies = b

The number of people, to whom supplies are provided = p

We get ;

`b+p=72`

Or

`p=72-b`
