A particular gas welding process in a confined space is suspected of producing dangerous concentrations of carbon monoxide, carb
on dioxide, iron oxide particulate, and manganese fumes. Atmospheric sampling produces the following exposure data:
Period CO (ppm) CO2 (ppm) Iron Oxide Manganese
(mg/m3) (mg/m3)
8:00 am - 10:00am 10 1000 1 1
10:00am - 12:00pm 20 1000 4 1
12:00pm - 1:00pm 25 1000 2 0
1:00pm- 4:00pm 30 1000 3 1
Do the calculations to determine whether the combined exposure represents an OSHA violation.

Answer:
The balance in the Sinking Fund immediately after repayment of the loan will be $2,133.19
Explanation:
Hi, John will pay the loan by paying the yearly interest and the rest is going to go to the sinking fund, so, if he has $1,627.45 and the annual interest of the loan are $1,000, he will be depositing $627.45 into the sinking fund for ten years. Therefore, the future value of the annual deposits of the sinking can be found by using the following formula.
Where:
A = equal annual savings into the sinking fund (that is $627.45)
r = effective rate of the sinking fund (14%)
n = 10 years
Everything should look like this.
Now, this is the balance after 10 years, but remember that John has to pay the loan, which is $10,000 (not $11,000 because John pays the interest of the loan and then deposits the balance into the sinking fund). Therefore, the balance after repaying the loan is $12,133.19 - $10,000 = $2,133.19.
Best of luck.
