Over the summer in Albany, New York, the depth of the local reservoir decreased 15 inches. If the water depth decreased by 3 inches each week, how many weeks did it take for this change to occur?

HELP ASAP THX

  1. The answer would be 5 weeks, because you can divide the 15 inches by 3 inches lost per week.

  2. Think of it as losing three inches every week for five weeks, so what times 3 would be equal to 15?
    5
