First step is to find z of 60% using the invNorm distribution

Hence,

z=0.6=0.2533

Now let Find P60 which is the score which separates the lower 60% from the top 40% using this formula

x<=>z

Where,

Standard deviation=50

Mean=200

z=0.2533

Let plug in the formula

x=0.2533*50+200

x=12.665+200

x=212.665

x=212.7(Approximately)

Therefore the score which separates the lower 60% from the top 40% is 212.7

Answer 1: y = 35x + 50

Answer 2: will

Answer 3: $10

Step-by-step explanation:

Equation: y = 35x + 50

Registration fee is one time, so you just add to it.

You have to pay each time you go to a session, so x will be the amount of sessions, 35 will be the price of each session.

You can plug in the 8 to the equation, then solve for y:

y = 35(8) + 50\\y = 280 + 50\\y = 330

They will be able to pay for it because: 330 < 340

They will have $10 left because:

340 - 330 = 10

340 is how much on the card and 330 is how much the 8 lessons (in total) cost.
