So PEMDAS is order of operations basicly.
P=Parenthesis
E=Exponets
M=Multiplication
D=Division
A=Addition
S=Subtraction
For example: 2x4+(9x9)-1
When solving order of operations you ALWAYS start with the problem in the parentheses.
(9x9)=81
Now multiplication comes next so, 2x4=8
Then addition, 8+81=88
Lastly subtraction, 88-1=81

Answer:
Pounds of apple used = 10,078.20
Pounds of taffy = 144.80
Step-by-step explanation:
Assume :
x = pound of taffy mixture
y = pounds of apple mixture
Total :
x + y = 10,223 - - - (1)
Proportion of apple to taffy
x / y = 1 / 69.6
Cross multiply :
y = 69.6x
(1) becomes :
x + 69.6x = 10223
70.6x = 10223
x = 10223 / 70.6
x = 144.80169
Put x = 144.80169 in
y = 10223 - x
y = 10223 - 144.80169
y = 10078.19831
Pounds of apple used = 10,078.20
Pounds of taffy = 144.80
Answer:
20/56 or 5/14
Step-by-step explanation:
Prob of red = 5/8
Second red prob = 4/7
multiply those = 20/56
simplify if needed = 5/14
