Question

Steps to solve this-- Find the percent of increase from 380 to 440. Round to the nearest tenth of a percent if necessary. 13.6% 15.8% 0.2% 86.4%

1 Answer

  • If 380 would be 100%

    Then use rule of 3

    380 ______ 100%

    440 ______ y

    380y = 440×100%

    380y = 440 × 1

    Dividing both the sides by 380

    y = 440/380

    y = 1,158

    Let's multiplity "y" by 100

    y = 115,8%

    As we did have 100% initially

    Then the increase will be

    The increase = 115,8% -100%

    = 15,8%
