Write About the Math
How much more can the detective spend? How much does each flashlight cost? When do you use an equation versus an inequality?¿Cuánto más puede gastar la detective? ¿Cuánto cuesta cada linterna? ¿Cuándo usas una ecuación y cuándo una desigualdad?
Say your answer to a partner first. Then write it, using at least two of these words:
Model: An exact total points to an equation; a limit or range points to an inequality. — Students use signal words ('equals/total' for an equation; 'at least/at most/no more than' for an inequality) to choose the correct model.
