A model estimates that whales from the genus Eschrichtius travel 72 to 77 miles in the ocean each day during their migration. Based on this model, which inequality represents the estimated total number of miles, x, a whale from this genus could travel in 16 days of its migration?
- 172 < 16x < 77
- 272 ≤ 16 + x ≤ 77
- 3(72)(16) ≤ x ≤ (77)(16)✓
- 472 + 16 ≤ x < 77 + 16
Correct answer
(72)(16) ≤ x ≤ (77)(16)
