Question

Bo and Erica are yoga instructors. Between the two of them, they teach 41 yoga classes each week. If Erica teaches 10 fewer than twice as many as Bo, how many classes does each instructor teach per week?

Answer 1

Let classes by erica = x
Then classes by bo =(41-x)
now
We have condition
2(41-x)-x = 10
82-2x-x=10
3x=82-10
3x=72
x= 24 = classes taken by erica
y=17 = classes taken by bo
