Elle decreased her monthly budget from $250 to $200. Calculate the percent decrease
kirill [66]
Formula for finding percent change (increase or decrease) is amount of the change divided by the original amount.

Here, the amount of the change is 50 and the original amount is 250.

50/250= 0.2

Multiply by 100 to get percent.

20% decrease (because budget went down)
