Reasoning and answer: Let x be Sara's height in inches. Joe is 6 + 2x inches tall. 120 = x + (6 + 2x). 120 = 3x + 6. 114 = 3x. x = 38 inches. Joe is 6 + 2(38) = 82 inches.
The answer: 82

Debbie used 4 * 2 = 8 feet of tape for the large boxes. She used 2 * 8 = 16 feet of tape for the medium boxes. She used 1 * 5 = 5 feet of tape for the small boxes. There were 2 + 8 + 5 = 15 boxes in all. She used 1 * 15 = 15 feet of tape for the address labels. Thus, she used 8 + 16 + 5 + 15 = 44 feet of tape in all.
The answer: 44
