Question

James is buying strings of lights to hang on his patio deck. He needs 90 feet of lights to go around the entire patio, but the lights he wants to buy are only sold in packs of 4 meters. If one meter is approximately 3.28 feet, how many packs of lights will James need for his patio?

1) 6 packs of lights
2) 7 packs of lights
3) 3 packs of lights
4) 10 packs of lights

Answer 1

After converting 90 feet to meters, we find that James needs a total of 27.44 meters of lights. Dividing this by the 4 meters per pack of the lights he wishes to purchase, we conclude he needs to round up to 7 packs of lights to cover his patio.

Step-by-step explanation:

The question is how many packs of lights James will need to cover a 90 feet patio with strings of lights sold in packs of 4 meters each. To solve this, first we convert the feet to meters to match the unit of the product he wants to purchase. Since 1 meter is approximately 3.28 feet, we divide 90 feet by 3.28 feet per meter.

90 feet / 3.28 feet/meter = 27.44 meters

Now, since the lights are sold in packs of 4 meters each, we divide 27.44 meters by 4 meters per pack to determine the number of packs he needs:

27.44 meters / 4 meters/pack = 6.86 packs

Since James cannot buy a fraction of a pack, he will need to round up to the nearest whole number. Therefore, James will need 7 packs of lights for his patio.
