1 answer:
Answer:
The total weight of the metal bar in pounds is 25 pounds
Step-by-step explanation:
Now, we have a metal bar which has a content of 60% zinc corresponding to 15 pounds.
Mathematically, let’s say the total weight of the metal composite is x pounds. It is 60% of this that is 15 pounds which is the content of the zinc
Mathematically;
60/100 * x = 15
60x = 15 * 100
60x = 1500
x = 1500/60
x = 25 pounds
