21. 5.25 x 4 = 21 inches Goran needs. 11 x 21 = 231 inches Natalie needs. 65.5 x 4 = 262 inches of total wood they have. 23 + 231 = 254 inches of wood used by both Goran and Natalie 262 - 254 = 8 inches of wood left over. So the answer for this would be D because 8 inches is not an answer given.
22. 6 x 12.6 = 75.6 total ounces of beans. 75.6 x .7 = 52.92 ounces of beans used in the stew. 75.6 - 52.92 = 22.68 ounces, so the answer for this would be D. Good Luck!
