Corbin earned $90 by working 10 hours at a grocery store. He earned $60 by working 6 hours at the library. Are these rates equivalent?

Respuesta :

No, he earns $10 an hour at the library and only $9 an hour at the grocery store, hope this helped
No, because he earned $10 for every hour at the library compared to $9 am hour at the grocery store.
