The winning times (in seconds) in a speed-skating event for men can be represented by the formula
T = 46.96 - 0.096x, where x represents the year, with x = 0 corresponding to 1920. (For example in 1992, x would
be 1992 - 1920 = 72.) According to the formula, what was the winning time in 1999? Round to the nearest
hundredth.

It is estimated that y, the number of items of a particular commodity (in millions) sold in the United States in year
x, where x represents the number of years since 1990, is given by the formula y = 1.29x + 4.37. That is, x = 0
represents 1990, x = 1 represents 1991, and so on. According to the formula, how many items sold in 1999?
A) 4.37 millions B) 50.94 millions C) 17.27 millions D) 15.98 millions
