Kaylee wants to do well in her classes so she is budgeting her time carefully to decide the number of
classes, "c," she can take this year. For each class that
she takes, she is expected to spend two and a half
hours each week working on homework. She expects
to spend an additional six and a half hours each week
completing the assigned reading for all of her classes
together. If Kaylee has 19 hours available each week
to complete homework and reading for her classes,
which equation best models the situation.
