A group of children are swimming in a pool. They start in the middle of the pool and swim 20 feet toward the right end of the pool. They then swim to a point x feet to the right of the middle of the pool. So far, the children have swum a distance of 45 feet. Formulate an absolute value equation to represent this situation. Then solve the equation. a. 45 = 2|20- x; x = 5 or x= 45

b. 45 = 20+2|20 – x|; x=45

c. 45 = 20+ |20 – x|; a. x = 45

d. 45 = 20 – |20 – x|; x = 5 or x = 45
