'The cost of 4 wall clocks and 5 alarm clocks is *2200. The cost of 5 ...
Cost of Clocks


  • Let the cost of one wall clock be x and the cost of one alarm clock be y

  • From the given information, we can form two equations:


    • 4x + 5y = 2200

    • 5x + 4y = 72300


  • Solving these equations, we get:


    • x = 14000/9

    • y = 4400/9




Cost of 8 Wall Clocks and 8 Alarm Clocks


  • Using the values of x and y, we can find the cost of 8 wall clocks and 8 alarm clocks:

  • 8x + 8y = 8(14000/9) + 8(4400/9) = 22400 + 35200/9 = 26133.33



Sum of Consecutive Integers


  • Let the first of the fourteen consecutive integers be x

  • Then the sum of the last seven integers is (x+7) + (x+8) + ... + (x+13) = 7x + 70

  • Given that the sum of the last seven integers is 161, we get:


    • 7x + 70 = 161

    • 7x = 91

    • x = 13


  • Therefore, the sum of the first seven integers is 1 + 2 + ... + 7 = 28
