Answer:
Let the present age of the man be x years.
Age of the man 15 years ago =(x−15) years and
Age of the man 15 years later =(x+15) years
According to the given condition, we have
(x+15)=2(x−15)
⇒x+15=2x−30
⇒x−2x=−30−15
⇒−x=−45 or x=45 years
Hence, the present age of the man is 45 years.

Answer:
The selling price would be 
.
Step-by-step explanation:
We have been given that a sports drink has a cost of $1.25.
We need to figure out the selling price of the sports drink so that the store is able to generate a profit of $0.50 per drink.
We know that profit is found by subtracting the cost of an item from selling price of the item. Therefore, selling price of the item can be found by adding the profit to the cost.
Therefore, the required selling price of the sports drink would be:
First, we get the standard error of the mean using
σm = σ / √N
= 5 / √100
= 0.5
Next, we subtract and add 1.96 standard deviations from the mean (since the confidence interval is 95%). So,
8 ±1.96 (0.5)
= 8 <span>± 0.98
The answer is
</span>E) 8±0.98
