Final answer:
To have proceeds of $750 after 10 months, Mary should ask for a loan amount of approximately $865.15 at a discount rate of 16%.
Step-by-step explanation:
To find the amount of the loan Mary should ask for, we can use the formula for discounting:
A = P(1 - rt)
Where:
A is the amount borrowed (to be determined)
P is the proceeds ($750)
r is the discount rate (16% or 0.16)
t is the time in years (10 months/12 months per year)
Plugging in the values:
A = $750 / (1 - 0.16 * (10/12))
Simplifying:
A = $750 / (1 - 0.1333)
A = $750 / 0.8667
A ≈ $865.15
Therefore, Mary should ask for a loan amount of approximately $865.15 to have proceeds of $750 after 10 months.
