In the equation y= 0.5(1.21)^x, y represents the number of snowboarders in millions and x represents the number of years since 1988. Find the year in which the number of snowboarders will be 10 million for the first time.

Step-by-step explanation:

Here, y = 10 million = 10000000

x = 88.19 years

The number of snowboarders will be 10 million for the first time in year 2076.
