The percentage of farmers using draft horses in their fields in country XYZ had been estimated to be p=84.217-0.6648x, where x is the number of years after 1910. During what year did this model predict that the percentage of farmers using draft horses will be 76%? Can somebody PLEASE tell me why u don't solve the problem using .76 rather than 76? I always thought to solve problems for percentages you were supposed to move the decimal twice to the left before you solve.
