Let x be the amount (in oz) of pure silver used in this alloy. Each ounce of the pure silver contributes a value of $30.48, so that the total cost of the amount of pure silver that gets used is $30.48x.
The same goes for the secondary alloy, where each ounce costs $21.35, so that 52 ounces of the alloy contributes a total cost of $21.35*52.
The final alloy has a total mass of (x + 52) ounces, and each ounce costs $24.76, so that this alloy's totat cost is $24.76*(x + 52).
So we have
30.48x + 21.35*52 = 24.76*(x + 52)
30.48x + 1110.20 = 24.76x + 1287.52
5.72x = 177.32
=> x = 31

Answer:
Cash remaining in the petty cash box = 20.99 dollars
Explanation:
Given that,
Petty cash has a balance of = 73.28 dollars
Total receipt = 52.29 dollars
We need to find the remaining petty cash .
In order to find out the remaining cash, we will subtract total receipt from Petty cash balance.
Cash remain = Petty cash balance - total receipt
Cash remain = $73.28 - $52.29
Cash remain = 20.99 dollars
That's the final answer.
I hope it will help you.

Answer:
A 35 pages per hour
Step-by-step explanation:
The rate of change is the slope
(0,150) (7,400)
m = (y2-y1)/(x2-x1)
=(400-150)/(7-0)
=250/7
=35.7 pages per hour
Approximately 36 pages per hour
