Answer:
Kunie is 25
Step-by-step explanation:
Let's make Yemi's age y, and Kunie's age k.
Because Yemi is 5 years older that Kunie, k + 5 = y.
Because the product of their ages is 750, k * y = 750.
With substitution, we can determine that k * (k + 5) = 750.
Then with distributive property we can simplify the equation to get k^2 + 5k = 750.
Then we bring all the terms to one side of the equation to get k^2 + 5k - 750 = 0.
Then with quadratics, we can factor the equation to get (k + 30)(k - 25)=0.
Thus, either k + 30 must equal 0, or k - 25 must equal 0. Thus, k must equal 25 or -30, and because someone cannot be -30 years old, k = 25.
Then, because Yemi is 5 years older than Kunie, y = 30.
