Answer:
13.42
Step-by-step explanation:
For the given numbers, the lowest bound : 41.66. the upper bound: 42.19
<h3>How are upper and lower boundaries discovered?</h3>
To determine a rounded number's upper and lower bounds: Determine the place value of the claimed level of accuracy. By two, multiply this place value. Find the upper bound by adding this amount to the provided value, and the lower bound by deducting this amount from the given value.
The lower: a=49.35. b=7.69
so the lower bounds is:
a-b=49,35-7.69 =41.66 = a=49.49.34.
b=755 the upper = a= So the upper bounds is = a-b= 42.79.

Based on the information given the gain or loss percent on the whole transaction is 1%.
<h3>Gain or loss percent:
</h3>
First step is to calculate the profit on the whole transaction
Profit=(8%×8,000)-(6%×8,000)
Profit=$640-$480
Profit=$160
Now let calculate the gain or loss percentage on the whole transaction
Gain or loss percentage=160/(8000+8000)×100
Gain or loss percentage=160/16000×100
Gain or loss percentage=1%
Inconclusion the gain or loss percent on the whole transaction is 1%.
