You are doing annual inventory at the hardware store where you work. A box filled with brass connectors weighs 5 pounds 4 ounces
Georgia [21]

Answer:

304 brass connectors.

Step-by-step explanation:

We have been given that a box filled with brass connectors weighs 5 pounds 4 ounces. The box weighs 8 ounces when empty, and each connector weighs 0.25 ounces.  

Since we know that 1 pound equals to 16 ounces.Let us convert weight of box filled with brass connectors from pounds to ounces.

(5*16)+4=80+4=84

Now we will find weight of brass connectors by subtracting weight of empty box from weight of filled box.

84-8=76

Let us divide 76 by 0.25 to find number of brass connectors in the box.

\text{ Number of brass connectors in the box}=\frac{76}{0.25}

\text{ Number of brass connectors in the box}=304

Therefore, there are 304 connectors in the box.
