Final answer:
To find the number of books the store will wrap in 7 days using the ribbon from two rolls, calculate the total ribbon used and then divide it by the length of each roll. Answer choice B) 190 books is closest to the calculated value.
Step-by-step explanation:
To calculate the number of books the store will wrap in 7 days, we need to find the total ribbon used by the store first. The store uses 2 3/8 feet of ribbon for each book and goes through 2 rolls of gift wrap every day. So in one day, the store uses 2 x 2 3/8 = 4 3/4 feet of ribbon. In 7 days, the store will use 7 x 4 3/4 = 33 1/4 feet of ribbon. Since each roll is 265 1/2 feet long, we can divide the total ribbon used (33 1/4 feet) by the length of each roll (265 1/2 feet) to find the number of rolls used. 265 1/2 ÷ 33 1/4 = 8. Therefore, the store will wrap 8 rolls x 2 rolls = 16 rolls of books in 7 days. Answer choice B) 190 books represents the closest option to this calculation.
