A box of light bulbs is shipped to a hardware store. When it arrives, 4 of the bulbs are broken. Predict the number of broken light bulbs in an order of 125 bulbs.

Respuesta :

As 4 of 25 light bulbs are broken you use a rule of three to find the number of broken bulbs in a order of 125:

[tex]x=\frac{125\cdot4}{25}=\frac{500}{25}=20[/tex]Then, in a order of 125 bulbs the prediction is 20 broken bulbs
