The equation s = 4 × b is used to tell you how many screws you need based on how many pieces of wood you have. The total number of screws needed is represented by the variable s. The number of pieces of wood is represented by the variable b. If you have 6 pieces of wood, how many screws do you need in all? A.10 B.4 C.24 D.6
If b is the variable that represents the number of wood, then replace b with 6 and do the math. s = 4 * 6 s = 24. So, you would need 24 screws for the 6 boards of wood.
