Write About the Math

Would you recommend that Diamond purchase or stream songs from the online music service?¿Le recomendarías a Diamond comprar canciones o escucharlas en streaming del servicio de música en línea?

Say your answer to a partner first. Then write it, using at least two of these words:

equationecuación variablevariable ratetasa representrepresentar define the variablesdefinir las variables

Model: The fee is charged EVERY month, so the total must be the rate multiplied by the number of months, not added to it once. — A strong answer tests the equation against a table row (2 months should give $49.90) rather than just stating a rule. A weak answer picks multiplication without checking it against the actual numbers.
