2.5 b + 5 r = 80 The given equation describes the relationship between the number of birds, b ,

Question

2.5 b + 5 r = 80 The given equation describes the relationship between the number of birds, b , and the number of reptiles, r , that can be cared for at a pet care business on a given day. If the business cares for 16 reptiles on a given day, how many birds can it care for on this day?

Accepted Answer

Choice A is correct. The number of birds can be found by calculating the value of b when r = 16 in the given equation. Substituting 16 for r in the given equation yields 2.5 b + 5 16 = 80 , or 2.5 b + 80 = 80 . Subtracting 80 from both sides of this equation yields 2.5 b = 0 . Dividing both sides of this equation by 2.5 yields b = 0 . Therefore, if the business cares for 16 reptiles on a given day, it can care for 0 birds on this day. Choice B is incorrect and may result from conceptual or calculation errors. Choice C is incorrect and may result from conceptual or calculation errors. Choice D is incorrect and may result from conceptual or calculation errors.
