Mr. Russell and Ms. Nicholson are teaching their classes how to write in cursive. Mr. Russell has already taught his class 2 let
ters. The students in Ms. Nicholson's class, who started the unit later, currently know how to write 4 letters. Mr. Russell plans to teach his class 3 new letters per week, and Ms. Nicholson intends to cover 2 new letters per week. Eventually, the students in both classes will know how to write the same number of letters. How long will that take?
