how do you set up a money percent problem?

OpenStudy (anonymous):

you mean ?

OpenStudy (anonymous):

$50 is 50% of $100

OpenStudy (anonymous):

60% = 60/100

OpenStudy (amistre64):

depends on the problem

OpenStudy (karatechopper):

well here is the problem: a sweater is marked down from an original price of $45 to $33.75. By what percent has the original price of the sweater been marked down

OpenStudy (anonymous):

75%

OpenStudy (amistre64):

there are 3 parts to most percentage problems; a total or whole amount; a part of that total; and a percentage number. when we know any 2 elements we can find the third by using the formula: part = % times whole

OpenStudy (karatechopper):

thanx!

OpenStudy (curry):

hey amis can you please help me when you are done here

OpenStudy (amistre64):

since they give a total(45) and a part(33.75) and are asking for percent; we can solve the formula above for % part ---- = % ; well, a decimal version of % that is; multiply it by total 100 to get a normal % format
