23) Refer to the scenario given below to answer the following question: Which inequality describes the part of Highway 8 where both radio stations can be received? State the letter of the correct answer. Radio station WMAT in Math City is 200 miles from radio station WGEO in Geometry City.  Highway 8, a straight road, connects the two cities. 

WMAT broadcasts can be received up to 150 miles in all directions from the station and WGEO broadcasts can be received up to 125 miles in all directions.  Radio waves travel from each station through the air, as represented below.

Print out and complete the drawing below to show the part of Highway 8 where both radio stations can be received.  Think of station WMAT being located at mile marker 0 and station WGEO located at mile marker 200. Add numbers to the number line at each hash mark, equally-spaced divisions of Highway 8.
