Answer:
99.8% is the percent of bags contain between 62 and 86 potato chips.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 74
Standard Deviation, σ = 4
We are given that the distribution of number of potato chips in a bag is a bell shaped distribution that is a normal distribution.
Formula:
P( bags contain between 62 and 86 potato chips)
Answer:
0.15x=x-30
Step-by-step explanation:
Let
x-----> the regular price
we know that
15%=15/100=0.15
so
0.15x=30
x=30/0.15=$200
<em>Verify each case</em>
case a) 0.15x=30
x=30/0.15=$200
therefore
The equation could be used to determine x
case b) 0.85x=x-30
x-0.85x=30
0.15x=30
x=30/0.15=$200
therefore
The equation could be used to determine x
case c) 0.15x=x-30
x-0.15x=30
0.85x=30
x=30/0.85=$35.29
therefore
The equation could not be used to determine x
case d) x-0.15x=x-30
-0.15x=-30
0.15x=30
x=30/0.15=$200
therefore
The equation could be used to determine x
