This is sort of weird to write without any numbers, but it's not too hard. take your info out of the word problem:
fit fast = fee per class
stepping up = fee per class + monthly fee
now you just change all of that into variables, essentially:
F = cx
S = cx + m
so, fit fast is the cost of classes (c) times the number of classes taken (x). stepping up is the cost of classes times x, PLUS that additional monthly fee (m).
Answer:
-1.14
Step-by-step explanation:
The given information in statement is
mean=μ=69
standard deviation=σ=3.5
Let X be the Ishaan's exam score
X=65
The Z score can be computed as


z=-1.1429
z=-1.14 (rounded to two decimal places).
Thus, the computed z-score for Ishaan's exam grade is -1.14.
2,000 is the correct answer I am sure of it
