Final answer:
James needs to convert 90 feet of lights to meters, which equals 27.44 meters. Each light pack has a length of 4 meters, resulting in a need for 6.86 packs. Rounding up, James will need to buy 7 packs of lights.
Step-by-step explanation:
James needs 90 feet of lights for his patio and is looking to buy packs of lights that are each 4 meters long. To determine how many packs of lights he needs, first, we need to convert the 90 feet of lights into meters. Since 1 meter is approximately 3.28 feet, we have:
90 feet ÷ 3.28 feet/meter = 27.44 meters
Since one pack of lights is 4 meters long, we divide the total number of meters needed by the length of each pack:
27.44 meters ÷ 4 meters/pack = 6.86 packs
However, since James cannot buy a fraction of a pack, he will need to purchase 7 packs to ensure he has enough lights to cover the entire 90 feet of his patio.
