Q. Every year, Spencer's grandmother knits him a cozy wool sweater for his birthday. Spencer's favorite color is red, so she plans to buy 700700 yards of thick red wool for his sweater this year. She chooses a wool that is sold in 420420-foot skeins, or bundles. How many skeins should she buy?\newlineWrite your answer as a whole number, decimal, or simplified fraction. Do not round.\newline____ skeins
  1. Convert Wool to Feet: Convert the required wool from yards to feet.\newlineWe know that 11 yard is equal to 33 feet. Spencer's grandmother needs 700700 yards of wool for the sweater.\newline700 yards×3 feet/yard=2100 feet700 \text{ yards} \times 3 \text{ feet/yard} = 2100 \text{ feet}
  2. Determine Skein Length: Determine how many feet are in one skein.\newlineThe wool is sold in skeins of 420420 feet each.
  3. Calculate Number of Skeins: Calculate the number of skeins needed.\newlineTo find out how many skeins are needed, divide the total amount of wool required in feet by the number of feet in one skein.\newline21002100 feet / 420420 feet/skein = 55 skeins
