Answer:
1 apple costs $1.2
1 pear costs $1
Step-by-step explanation:
Represent Apples with A and Pears with P
For the person in my front, the expression is:
For me, the expression is
Hence, the system of equation is:
Solving for the values of A and P.
Substract equation (2) from (1)
<em>Hence, 1 pear costs $1</em>
Substitute 1 for P in
<em>Hence, 1 apple costs $1.2</em>
The % margin of error means that the real value is in the range between the mean less the margin error and the mean plus the margin error. This is [ mean - % of error, mean + % of error]. Then, in this case the error of +/- 2% means that the expected population proportion that wants flexible working hours is between 60% - 2% and 60% + 2%, which is between 58% and 62%.
