For 1980 through 1990, the average weekly earnings (in dollars)for workers in the United States can be modeled by E= 14.5t + 270, where t is the number of years since 1980. Approximate the average weekly earnings in 1980 and 1990.

I am having trouble understanding what I have to do for this problem. Please help me as soon as possible! Thanks.

Year t Earnings(15.5t+270)

1980 0 270

1981 1 285.5

1982 2 ....

1990 10

So fill in the table, or just use the formula. The key is to compute t. t=Year-1980
