Help with PEMDAS?

OpenStudy (unicornpoopcookies):

So the problem is (1 and 1/2 *fraction* x$8.40) x 7

OpenStudy (jhannybean):

Parenthesis > exponent > Multiplication > Addition > Subtraction

OpenStudy (unicornpoopcookies):

I keep getting 88.20 but the answer is 85.00???

OpenStudy (jhannybean):

\[1\frac{ 1 }{ 2 }*$8.40*7\]?

OpenStudy (unicornpoopcookies):

Yes only the 1 and one half and 8.40 are in a parenthesis

sam (.sam.):

The problem with pemdas is it doesnt work, dont follow pemdas, just multiply everything

OpenStudy (jhannybean):

BREAK THE RULES! CHALLENGE THE SYSTEM!

OpenStudy (unicornpoopcookies):

Its still 88.2

OpenStudy (jhannybean):

Then 88.2 is your answer.

OpenStudy (unicornpoopcookies):

No the answer is 85.00

OpenStudy (unicornpoopcookies):

I wan to know whyyy

OpenStudy (jhannybean):

it's not 85.00...\[(\frac{ 3 }{ 2 })(8.40)(7)=88.2\]

OpenStudy (unicornpoopcookies):

According to the answer booklet it is 85.00

OpenStudy (unicornpoopcookies):

another problem i have is : (1 and one fourth x $6.00 ) x 9

OpenStudy (jhannybean):

\[\frac{5}{4}*6.00* 9\]\[(\frac{5}{4})*(54)\]

OpenStudy (unicornpoopcookies):

This is really irritating because

OpenStudy (unicornpoopcookies):

I do it a million ways for this one i got 67.5

OpenStudy (unicornpoopcookies):

but the answer is 0.5

OpenStudy (unicornpoopcookies):

OpenStudy (unicornpoopcookies):
