Step-by-step explanation: If brianna earns $5 each week for walking her neighbor's dog and she does it for 7 weeks, you have to multiply 5 by 7 to figure out how much she earns.
Since she earns $5 a week you would have to take 5 and multiply it by how many weeks she has walked her neighbors dog. In this case it would be 5 times 7 to get 35.
