Joe's electric made 16 customer calls last week and 22 calls this week. How many calls must be made next week in order to maintain an average of at least 21 calls for the three week period?

My answer was at least 19 calls must be made to maintain an average of 21 calls is this correct?

  • Math - ,

    3 * 21 = 63 calls in 3 weeks

    16 + 22 = 38 calls made in 2 weeks

    63 - 38 = 25 calls next week



    Check it out: 16 + 22 + 25 = 63

    63/3 = 21
