Kali Porter · Answer 1

If there are 840, then you can multiply it by 1.05 to get the answer. This is the same as finding 5% of 840 and then adding that to 840, but this does it in one computation. 840 * 1.05 = 882

The current population would be 882.

Dottie · Answer 2

840

10% = 84 (840/10)

5% = 42 (84/2 or 840/20)

therefore 840+42=882
