A company has determined that the number of items it sells varies inversely as the price of the item. If 20,000 items can be sol
mestny [16]
Let N be the number of items sold and p the price. 
Since the variation is inverse, then the relation between N and p is:
N=k\dfrac{1}{p}
For N=20000 and p = $9.5, we get the formula:
 20000=k\dfrac{1}{9.5}\\p=20000\times9.5=190000
If p = 8.75, then the number of items sold can be computed using the formula:
N= 190000\dfrac{1}{8.75}=21714 \text{ total items}

Answer:

  3 months

Step-by-step explanation:

We don't know what's on your list of "useful financial formulas." One that can be used here is the formula for simple interest:

  I = Prt . . . . . interest on principal P at annual rate r for t years

Solving for t gives ...

  t = I/(Pr)

Filling in the given values, we can find t to be ...

  t = 138/(4800×0.115) = 138/552 = 1/4

1/4 year is 3 months -- the duration of the loan.
