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

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