Dupe's present age = 14 years
Olu's present age = 11 years
Explanation:
- Let Dupe's age be x. Let Olu's age be y. Since their ages add up to 25 years, x + y = 25
- Eight years ago Dupe's age was double that of Olu's age. Solving by simultaneous equations. Four methods are Elimination Method, Graphical Method, Substitution Method, and Matrix Method. Let us try out Elimination method for solving a pair of simultaneous linear equations that reduces one equation to one that has only a single variable. Once this has been done, the solution is the same as that for when one line was vertical or parallel.
- Therefore, eight years ago, Dupe's age was 6 and Olu's age was 3 so that x=2y becomes, 6=2*3. Eight years hence, x=6+8=14 and y=3+8=11. That makes, x or Dupe's age as 14 years and y or Olu's age as 11 years.

Answer: 0%
Explanation:
Elasticity measures the change in demand resulting from a change in price. The law of demand holds that when prices increase, quantity demand would decrease and elasticity is meant to show the magnitude of this change.
A unit elastic good means that prices and quantity demanded change by the same amount. This means that for a unit elastic good, if the price change is a 5% increase, the quantity demanded will decrease by 5%.
In terms of revenue, if the price increases by the same amount that quantity demanded decreases, the effects will cancel out so there will be no revenue effect.
Artificial selection is the intentional reproduction of individuals in a population that have desirable traits. In organisms that reproduce sexually, two adults that possess a desired trait — such as two parent plants that are tall — are bred together.
