Step-by-step explanation:

The scenario illustrates that the weight for people who exercises regularly tends is normal or below normal.

John's income increased by 4%. if his income rose by $850, find his previous amount​
bearhunter [10]

Answer:

$21,250

Step-by-step explanation:

4% = 850

100% = x

Cross multiply the above to get 21,250

Another way of doing this is:

850 divided by 4 = 212.5

So every percent is equal to 212.5, so:

212.5 * 100 (for 100%) = 21,250
