A company rents cars at $45 a day and 12 cents a mile. A second rental company's cars are $60 a day and 5 cents a mile. (a) For each company, give a formula for the cost of renting a car for a day as a function of the distance traveled. Assume distance m is measured in miles. Assume cost C is measured in dollars. First company: C1(m) = Second company: C2(m) (b) Drag the point to select the correct graph of both functions. 2$ 100 90 80 70 60 50 40 30 Choose one 20 10 miles 50 100 150 200 250 300 350 cheaper? Find the (c) How should you decide which company number of miles driven which gives the same cost of renting for both companies. NOTE: Round to the nearest whole number.

A new building that costs $1,000,000 has a useful life of 100 years and a scrap value of $500,000. Using straight-line depreciation, find the equation for the value V in terms of t, where t is in years. Find the value after 1 year, after 2 years, and after 90 years.V(t) =        value after 1 year   $  value after 2 years   $  value after 90 years   $

A. Representing Functions Juan is working as a seller of salted eggs, His boss lets him sell it for 15 pesos per piece, and which is not the real price of it, for him to have an additional income to his 200 pesos working salary that his boss always gives him. What will be the equation/s in finding the amount of his income per day considering that the real price of the salted egg is only 13 pesos? Representations: I- Total income per day E- Number of salted eggs sold 1. Which do you think is the independent variable? 2. Which do you think is the dependent variable? 3. What will be the equation for Total income per day? 4. What will be his Total Income, if he sold 200 pieces in a day? 5. How about if he has no sales in a day? 6. Create new equations for his (a.) daily SALES and (b.) his total daily income if his boss sets discounts such that every 3 eggs will cost 40 pesos. (he will be given 4 pesos per 3 salted eggs)
