Anew car was sold with new brake linings that were each 0.250 inch thick. after the car had been driven 50,000 miles without replacing any brake linings, the thinnest brake lining was 0.085 inch thick. what was the percent decrease in the thickness of the thinnest brake lining?

Percent decrease will be 66 %

Step-by-step explanation:

We have given that initially the thickness of the brake = 0.250 inch

And after driving 50000 miles thickness of the brake = 0.085

We have to calculate percent decrease in thickness of the brake

We know that percent decrease is given by

So percent decrease will be 66 %

341

step-by-step explanation:

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.
