Question

It costs $3.56 to buy a pack of pencils. Which of the following equations shows the amount of money needed, x, to buy k packs of pencils?
x = 3.56k
k = 3.56x
x = 3.56 + k
k = 3.56 + x

Answer 1

The total price would be $3.56 times however many you bought, so the correct equation would be x = 3.56k.
