The judges at a cheerleading competition use the rule that 240 represents the length of the routine in seconds, but the final length of the routine can be 5 seconds higher or lower than 240. How would you
find the equation or inequality that gives the range of seconds allowable for the routine, and what is the
range?
A. Write the range of seconds as x = 235 or x = 245. Combine these to write the equation
as (x - 51- 240.
B. Write the range of seconds as 240 sx. Then rewrite the equation as (x - 240- 5.
C. Write the range of seconds as 235 sx s 245. Combine these to write the equation as
1x - 2401-5.
D. Write the range of seconds as x s 245. Then rewrite the equation as x - 240 - 5.
