Answer:
b) The value of Bettina's expression is 4 times more than the value of Nikita's expression.
Explanations:
Nikita's expression = 72 + 26
Bettina's expression = 4 x (72 + 26)
For clarification, let us find the value of Nikita's expressions
Value of Nikita's expression = 72 + 26 = 98................(1)
Let us simplify Bettina's expression a little further:
Bettina's expression = 4 x (72 + 24)
Bettina's expression = 4 x 98 ..........................................(2)
Comparing equations (1) and (2), we would see that the value of Bettina's expression is 4 times the value of Nikita's expression.
