Q:
# Four photographers are taking pictures at a school dance. Photographer A takes 25 of the pictures, Photographer B takes 4% , Photographer C takes 0.29 , and Photographer D takes 27100 . Which choice lists the photographers in order from least to greatest by the amount of pictures they take?

Accepted Solution

A:

Let

x----------> number total of pictures

we know that

A------>25

B------> 4%----> 4/100------> 0.04x

C-----> 0.29------> 29%-------------------> 0.29x

D------> 27/100 --------> 27%--------------> 0.27x

[B+C+D]=4%+29%+27%--------> 60%

that means A=100%-60%---------> 40%

so

A-------------> 0.40x

A------>0.40 xB------> 0.04xC-----> 0.29xD------> 0.27x

the answer is

the photographers list in order from least to greatest by the amount of pictures they take is

B------> 0.04x

D------> 0.27x

C------> 0.29x

A------> 0.40x

x----------> number total of pictures

we know that

A------>25

B------> 4%----> 4/100------> 0.04x

C-----> 0.29------> 29%-------------------> 0.29x

D------> 27/100 --------> 27%--------------> 0.27x

[B+C+D]=4%+29%+27%--------> 60%

that means A=100%-60%---------> 40%

so

A-------------> 0.40x

A------>0.40 xB------> 0.04xC-----> 0.29xD------> 0.27x

the answer is

the photographers list in order from least to greatest by the amount of pictures they take is

B------> 0.04x

D------> 0.27x

C------> 0.29x

A------> 0.40x
