Answer:
250
Step-by-step explanation:
Bulb box and carton both are of cuboidal shape.
<u>For bulb </u><u>box</u><u> </u><u>the </u><u>d</u><u>imensions</u><u> </u><u>are:</u>
- l = 5 cm, w = 4 cm, h = 4 cm
<u>For </u><u>Carton </u><u>the dimensions are</u><u>:</u>
- l = 50 cm, w = 20 cm, h = 20 cm
To find the number of bulbs packed in the carton, divide the
by 
So, 250 bulbs will be packed in one carton.
−3b+2.5=4
Subtract 2.5 from both sides.
−3b+2.5−2.5=4−2.5
−3b=1.5
Divide both sides by -3.
−3b/−3 = 1.5/−3
b=−0.5
