Kowalski’s drug store signed a 15-month simple discount note with a face value of $12,300. find the proceeds if the discount rate is 12%. $9,840 $12,115.50 $10,455 $1,845 find the effective rate of interest (apr) for a loan with a loan amount of $17,300, a time of 180 days, and interest of $1,297.50. 11.5% 20% 3.2% 15% discount is the loan amount. true false i need , its due today. i can't get them wrong and you will mark brainliest

A.  Using the Simple Discount Note formula:
     Proceeds = Maturity Value (MV) - Discount; MV = Face Value
     Discount = MdT; M = Maturity; d  = discount; T = Time
                    = $12,300*12%*15/12
     Discount = $1,845
     Proceeds = MV - Discount
                     = $12,300 - $1,845
     Proceeds = $10,455

B. Using the Simple Interest Note formula:
    Effective Rate of Interest = Interest / Proceeds*Time
                                            = $1,297.50 / $17,300*180/360
                                            = .15
    Effective Rate of Interest = .15 or 15%

C. False. Discount is the interest charged to the principal of the loan.
