The relationship between Priscilla's and Mary's age illustrates algebraic expression
The correct representation of the statements is b - k = 15
From the question, we have:
Priscilla = k
Mary = b
Mary = 15 years older
The third highlight above means that:
Mary = 15 + k
Substitute b for Mary
b = 15 + k
Subtract k from both sides
b - k = 15
Hence, the correct representation of the statements is b - k = 15
