a regulation professional basketball is to be inflated to 8 pounds per square inch with a margin of error of 0.2 pound per square inch. Write and solve an equation to find the minimum and maximum air pressure to which the basketball can be inflated
Suppose that the pressure in the basketball is given with x. Then, x cannote be more than 0.2 away from 8.
This can be written as an equation with absolute value function:
