Question

Bo and Erica are yoga instructors. Between the two of them, they teach 43 yoga classes each week. If Erica teaches 11 fewer than twice as many as Bo, how many classes does each instructor teach per week?

Answer 1

Erica teaches 32.33 or 32 classes

Bo teaches 10.67 or 10 classes

Explanation:

B + E = 43

E - 11 = 2B

B + E = 43

E = 43 - B

E - 11 = 2B

(43 - B) - 11 = 2B

B = 10.67 = 10

B + E = 43

(10.67) + E = 43

E = 32.33 = 32
