Assume the gasoline version of a Honda Civic costs $21,000 and gets 35 MPG while the hybrid version costs $26,500 and gets 47 MPG. Assume you drive 11,000 miles per year and gasoline costs $2.90 per gallon. Let G be the purchase cost plus the gasoline cost for x years of the gasoline versions and H be the purchase cost plus the gasoline cost for x years for the hybrid version of the Civic. a. Give G and H as equations in terms of x. b. Give the graphs of the equations from (a) on the rectangular coordinate axes system using a horizontal axis scaled in years from 0 to 50 and a vertical axis scaled in dollars from $20,000 to $50,000. c. How many years will be required to break even on the extra cost of the hybrid? What part of the graph exhibits this answer?
Working as an insurance salesperson, Ilya earns a base salary and a commission on each new policy,so Ilya’s weekly income, II, depends on the number of new policies, n, he sells during the week. Last week he sold 3 new policies, and earned $760 for the week. The week before, he sold 5 new policies, and earned $920.

4. North Babylon High School had four members on their cross country team in 2014. Over the next several years, the team increased by an average of 6 members per year. The same school had 16 members in their orchestra in 2014. The orchestra saw an increase of 4 members per year. Write a system of equations to model this situation, where xrepresents the number of years since 2014. Graph this system of equations below.
