7) A service station charges $40 per hour for labor plus the cost of parts to repair a car. Parts can either be ordered from the car dealership for $300 or from a parts supplier for $200. Write two equations that give cost C (in dollars) for a repair that takes t hours using parts from the dealership or from the warehouse. (ML A1) Answer: math \ C(t)=40t+300\\ \ C(t)=40t+200 math

8) Watch this [|video] about aquaculture (the farming of fish and other aquatic animals). World aquaculture increased at a relatively constant rate from 1991 to 2002. In 1994 world aquaculture was about 20.8 million metric tons. In 2000 world aquaculture was about 35.5 million metric tons. Write an equation that gives the world aquaculture (in millions of metric tons) as a function of the number of years since 1991. In 2001 China was responsible for 70.2% of world aquaculture. Approximate China's aquaculture in 2001. Answer: math \ A(t)= 2.45x+13.45 math In 2001 China should have produced about 26.64 million metric tons of fish from aquaculture.
