Emily takes different routes when she rides her bike to school each day. Going home, she always takes the same 4-mile route.
write an algebraic expression to represent the total distance Emily travels each day. Explain how you chose the variable and what the variable represents?
d= total distance m= distance biked in the morning
d= m+4
I chose the variable "m" to represent the varying distance that Emily bikes in the morning to school. Then I added 4 because her distance home from school is constant.
