person's adult height can be guessed from knowing his/her shoe size by the equation H= 1.6s + 4.3 where H is the person's adult height in feet and s is the persons shoe size. this equation has a margin of error of ±3.5 inches.
for the problems below, the example of the shoe size used will be size 13.

write answers rounded to 3 decimal places.

A) write an absolute value inequality (tolerance) that describes the person's possible heights. (height is in feet; error is in inches - convert inches. into feet)

b) solve the inequality and find the range of heights possible
