Q. 3 erasers cost $4.41.Which equation would help determine the cost of 4 erasers?Choose 1 answer:(A) x4=3$4.41(B) $4.414=3x(C) 34=x$4.41(D) x4=$4.413(E) None of the above
Define Cost of Eraser: Let's denote the cost of one eraser as x dollars. Since 3 erasers cost ($4.41), we can write the equation for the cost of 3 erasers as 3x=($4.41). To find the cost of 4 erasers, we need to determine the cost of one eraser first and then multiply it by 4. So, the equation will be 4x= cost of 4 erasers.
Calculate Cost of 1 Eraser: We can rearrange the equation 3x=$(4.41) to solve for x, the cost of one eraser. Dividing both sides by 3 gives us x=$(4.41)/3. This will give us the cost of one eraser.
Find Cost of 4 Erasers: Now that we have the cost of one eraser, we can find the cost of 4 erasers by multiplying the cost of one eraser by 4. The equation for this is 4x=4×($(4.41)/3).
Analyze Answer Choices: Looking at the answer choices, we need to find the one that represents the equation 4x=4×($4.41/3). Choice (A) (4/x)=($4.41/3) is incorrect because it suggests dividing 4 by the cost of one eraser, which is not what we want. Choice (B) (4/$4.41)=(x/3) is incorrect because it suggests dividing 4 by the total cost of 3 erasers, which is not the relationship we're looking for. Choice (C) (4/3)=($4.41/x) is incorrect because it suggests a ratio between the number of erasers and not their costs. Choice (D) (4/x)=(3/$4.41) is incorrect because it inversely relates the number of erasers to the cost of 3 erasers. None of these choices correctly represent the equation 4x=4×($4.41/3).
Select Correct Answer: Since none of the provided choices match our derived equation 4x=4×($4.41/3), the correct answer must be (E) None of the above.
