extended problem solving the tread depth of the tires on your family’s new car is 3÷8 inch you predict that as a re4sult of driving the car the change in tire tread depth will be about -3÷64 inch per year a) analyze write a variable expression for the tire read depth after y years of driving use your expression to make a table showing the tire tread depth after 1,2 and 3 years b) apply tires should be repleaced when the tread depth is 1÷6 inch extend your table from part (a) to find the approximate number of years the car can be driven before the tires beed to be repleaced
