Question

Question 2 of 15 An alloy has a 3:2 ratio of zinc to silver. What is the average cost of the alloy if zinc costs $10 per pound and silver costs $20​

Answer 1

Answer:

what's the mass of the alloy

if it's 15 than

cost of zinc = 90$

cost of silver = 120$

Answer 2

The average cost of alloy=36

Alloy $3:2 =zinc :silver$

The average cost of alloy, per pound

Zinc = $10

Silver =$20

$Average = \frac{Sum of all metals}{total number of metals}$

Average=$\frac{3*10+2*20}{2}$

Avg=$\frac{30+40}{2}$

Avg=$\frac{70}{2}$

The average cost of alloy =35

Average -It is the sum of all elements by a total number of all elements.
