Accepted Answer

Choice A is correct. Let x represent the number of rabbit snails that Naomi bought. It&rsquo;s given that each rabbit snail costs $ 8 . Therefore, the total cost, in dollars, of the rabbit snails that Naomi bought can be represented by the expression 8 x . It&rsquo;s also given that each nerite snail costs $ 6 , and that Naomi bought 2 nerite snails. Therefore, the total cost, in dollars, of the nerite snails that Naomi bought is 6 2 , or 12 . Since Naomi bought both the rabbit snails and the nerite snails for a total of $ 52 , the equation 8 x + 12 = 52 can be used to represent the situation. Subtracting 12 from both sides of this equation yields 8 x = 40 . Dividing both sides of this equation by 8 yields x = 5 . Therefore, Naomi bought 5 rabbit snails. Choice B is incorrect. This is the total cost, in dollars, of the nerite snails that Naomi bought, not the number of rabbit snails. Choice C is incorrect. This is the cost, in dollars, of one rabbit snail and one nerite snail, not the number of rabbit snails that Naomi bought. Choice D is incorrect and may result from conceptual or calculation errors.
