Question

Bo and Erica are yoga instructors. Between the two of them, they teach 45 yoga classes each week. If Erica teaches 12 fewer than twice as many as Bo, how many classes does each instructor teach per week?

Answer 1

Answer:

Let the number of Yoga Classes teach by Bo = x

Let the number of classes teach by Erica = y

Now ATQ.,

x+y = 45.

=> x = 45 - y Eq number 1

And

y = 2x - 12. Eq number 2

By putting the value of Eq 1 in 2. we Get.,

y = 2(45-y) - 12

y = 90 -2y -12

y = 78 -2y

3y = 78

y = 26

By putting the value of y in equation 1., we get,

x = 19

Bo teaches 19 classes while Erica Teaches 26.

bo has 20 erica has 25
