I can identify quantities that change together and write a rule.
The independent variable is the input you choose; the dependent variable changes with it. Define both and write the output in terms of the input. A table and graph must show the same rule and units.
A shop charges $5 for each of n notebooks. Name the independent and dependent variables and write a cost rule.
The chosen notebook count is the input; multiply it by price and add any fixed fee to get the cost.
A shop charges $3 for each of n notebooks plus a single $6 delivery fee. Name the independent and dependent variables and write a cost rule. What does the cost at n = 0 mean in this model?
The chosen notebook count is the input; multiply it by price and add any fixed fee to get the cost.
Work in order. Start with the foundations, then build toward explanation and application.
A shop charges $6 for each of n notebooks. Name the independent and dependent variables and write a cost rule.
A shop charges $2 for each of n notebooks. Name the independent and dependent variables and write a cost rule.
A shop charges $8 for each of n notebooks. Name the independent and dependent variables and write a cost rule.
A shop charges $4 for each of n notebooks plus a single $3 delivery fee. Name the independent and dependent variables and write a cost rule.
A shop charges $5 for each of n notebooks plus a single $3 delivery fee. Name the independent and dependent variables and write a cost rule.
A shop charges $3 for each of n notebooks plus a single $4 delivery fee. Name the independent and dependent variables and write a cost rule.
