Question

Find each percent of change. Round to the nearest whole percent if necessary. State whether the percent of change is an increase or decrease.

$180 to $210

Answer 1

so first we see if increase or decrease
180<210
it is increase

then we assume that
percent change
find how much change took place
210-180=30
30/180=x% change
percent means parts out ofo 100s so x%=x/100
30/180=x/100
multiply both sides by 100
3000/180=x
16.66666=x
answe ris 16.6%
