You can use find John's original earnings by taking 12% off of 5600. You can do this by doing 0.78 x 5600, and you get 4368.

Now, we can use John's orignal earning to find Musa's original earning. Knowing that their earning's correspond, you can use the proportion 5/3 = 5600/x. You can use cross products to solve:

4368 x 3 = 5x

13104 = 5x

2620.8 = x

Musa's original earnings was 2620.8.

If the sum of their new earnings is 9800, we can take of John's new earnings to find Musa's new earnings. 9800 - 5600= 4200. That means Musa's new earnings were 4200. To find the percentage, we can use the following equation, and then solve:

2620.8 = 4200x

.624 = x

That means that 2620.8 is 62.4% of 4200, and that it increased by 37.6%.
