In the year 1990, the average cost of a television could be modeled by the equation C = –10t2 + 1500
here t is the number of years since 1990. By the year
2000 the average cost had changed, so it could be
modeled by the equation C = –20t2 + 1000
Find the difference in the average costs for a television
between 2000 and 1990.
C=
Ε₯? +
