Question

9 pencils cost $7.74.Which equation would help determine the cost of 6 pencils?

Answer 1

Y=7.74/9×(6)

Explanation:

Here,we have the price of 9 pencils which costs $7.74 and to get the price of each one, we decide the total price by the number of pencils bought.

Therefore, $7.74/9(price of each pencil)

And then the price of 6 pencils will be: X= $7.74/9×(6)

Note that x is the price of each pencil.

Answer 2

The equation is x= (7.74 /9) 6

Explanation:

Hi, to answer this question we have to analyze the information given:

If 9 pencils cost $7.74, we have to divide the total cost ($7.74) by the number of pencils (9) to obtain the price of 1 pencil.

Now that we have the price of 1 pencil, to obtain the cost of 6 of them we simply multiply the result by six.

Mathematically speaking:

x= (7.74 /9) 6

Where:

x = Cost of 6 pencils in $

Solving:

x = 0.86 x 6 = $5.16
