In 1960, the world record for the men’s mile was 3.91 minutes. In 1980, the record mile was 3.81 minutes. Write a linear model that represents the world
record (in minutes) for the men’s mile as a function
of the number of years since 9160.
Use the model to estimate the record time in 2020
and 2040. How accurate is the 2020 estimate?

The answer is 270 cars.you can do this by making a proportional relationship. for instance, 200 is the whole we are using, so on a “number line” 200 would be over 100%. now, since he sells 35% more, add 35% to 100% to get 135% on the other side of the “number line” on the bottom half, leaving the top half empty.cross multiply 200 by 135 then divide by 100 to get your answer. i hope this , if it did, , if you don’t mind, giving me brainiest! 200/100% } 200 • 135 /100 ? /135%
