Applying Linear Equations
Model each situation with a linear function.
1.A gas station that fills portable propane tanks (such as are used for camping and for outdoor barbecues) charges $2.60 per gallon.
2.The weight of a bucket of golf balls is a function of the number of balls, each of which weighs 1.6 oz. The bucket itself weighs 2 lb.
3.It costs a farmer $110 to bring 150 pounds of tomatoes to market, and the tomatoes sell for $2 per pound. The difference between the income from sales and the cost is the farmer’s profit.
4.A newly-started high school hopes to enroll 80 students in its first year and to increase enrollment by 40 students per year over the next five years.
Write a linear function for each graph, and state and label the slope and the y-intercept in each case.
5. A caterer charges a flat fee to put on an event, plus a per-person cost based on how many guests attend.
