In 2010, a new type of computer was introduced and approximately 20 million were sold. In 2011, the number sold increased by a factor of approximately 4.5. Assuming that the sales follow a linear trend through 2016, approximately how many of these computers will be sold in 2016?

440 million computer sold

Step-by-step explanation:

in 2010 = 20 million sold

in 2011 = 4.5*20= 90 million sold

by linear equation formula

where y = computer sold in million

x=  year

putting in above equation and solving we get

\frac{x-10}{11-10}=\frac{y-20}{90-20}

70x-y=680

in 2016 put x= 16 ( assuming hat the sales follow a linear trend through 2016)

y = 70*16-680 = 1120-680= 440 million computer sold
