Annalise earns $4 an hour walking pets in her neighborhood. She evaluates the expression 4h, where h represents the number of hours, to find the amount she earns. Can any number be substituted for h? Explain.
Yes. Because h is however many hours she worked. so sometimes she may only do 1 hour, the next week she may do 20. So any number could be put in this equation. Hope this helps:)
