Members at a yoga school pay $10 per class plus a one time $100 membership fee. non members pay $15 per class. how many classes would a member have to take to save money compared to taking classes as a non-member?

show work

21 classes

Step-by-step explanation:

Let’s set up equations for both memebers and non-members!

Let c = classes

To find how many classes it would take to make the two things even, we set them equal.

10c+100 = 15c

Solving for c,

5c = 100

So c = 20.

Since you need 20 classes to break even, to save money as a member, you need 21 classes.

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %
