If 0 is t when the year is 1982, what
would be the value of t in 1990? How many
years is that? From 1982 to 1992 the cost of the manufacturing a PC has decreased by about the same percentage each year. The cost, C (in dollars), in year t can be modeled by C = 3440 * (3/4)^t
where t = 0 corresponds to 1982.
Find the ratio of the cost in 1990 to the cost in 1985.

t = 0 in 1982
t = 8 in 1990 that is 8 years later.
C = 3440 *(3/4)^0 = 3440
C = 3340 * (3/4)^8 = _____
Take the ratio of the ans for 1990 divided by the ans for 1985
