A. 19 Bo; 18 Erica

im good like that hehe

Answer 2

The correct answer is OD.

Explanation:

To find how many classes each instructor teaches per week, you need to set up and solve a system of equations based on the given information. In other words,

Let x be the number of classes Bo teaches per week and y be the number of classes Erica teaches per week.

The first equation is based on the total number of classes they teach

x + y = 37

The second equation is based on the relationship between their numbers of classes

y = 2x - 14

To solve this system, you can use substitution or elimination methods. For example, using substitution, you can plug in y = 2x - 14 into the first equation and get

x + (2x - 14) = 37

Simplify and solve for x

3x - 14 = 37

So, Bo teaches 17 classes per week and Erica teaches 20 classes per week.
