Signs are placed at the beginning and at the end of a 4-kilometer hiking trail. Signs are also placed every 500 meters along the trail. How many signs are along the trail? Explain. Since 4 kilometers is equal to 4000 meters, the equation m times 500 equals 4 comma 000 can be written to find the number of signs after the beginning sign. Then, since mequals 7 signs after the beginning sign, there are a total of 8 signs on the entire trail. (Type whole numbers.)
