Answer:
291.9518 metric Ton
Explanation:
Hello
according to the data provided by the problem.
Total Iron needed to build the railing (A)= 470.89 Ton
Total Iron purchased by the factory =0.38 of total
Total Iron purchased by the factory =0.38 *470.89
Total Iron purchased by the factory (B)=178.9382metric Ton
the difference between the total iron needed and the iron supplied by the factory will be the iron we need to get
A-B=iron we need to get(c)
C=A-B
C=470.89-178.9382
C=291.9518 metric Ton
Have a great day.
