Answer:
I believe D is the correct answer.
Step-by-step explanation:
Answer. 68%
Explanation: divide 17 by 25 and you will get .68 which you convert to a percent
Quantity equation: t + s = 48kg
Copper equation: 23t + 79s = 44*48
Multiply the quantity equation by 23 to set the problem up for the elimination method.
23t + 23s = 23*48
23t + 79s = 44*48
Subtract to solve for s.
56s = 21*48
s = 18 [Number of 79% bars needed]
t = 48 - 18 = 30 [Number of 23% bars needed]
