Model Linear Functions

A waitress ears $100 every week plus tips from customers.  She can only keep 75% of the tips that she earns each week.  Which linear function below best models the relationship between the amount of money the waitress earns(M) and the amount of tips(t) she receives?  How much money would she earn in a week if she receives $252 in tips?

• M = 0.75t + 100 and $289

• M = 0.75t + 100 and $189

• M = 75t + 100 and $289

• M = 100t + 75 and $25,275

What type of function describes the story below?

Amy had $10 in her piggy bank. She added $5 each week.

• Linear because this has a constant rate of change.

• Exponential because this grows at a constant percent rate

• Quadratic because this is an area model.
