(Solved): for first question k is 6pls solve both questions with full steps 1. Calculate the following unknown ...

1. Calculate the following unknown quantities. (a) \( P=(k \times 1000), r=1.2 \%, t=\frac{250}{365} \). Find \( S \). (b) \( P=1440, S=1500, r=k \% \). Find \( t \) in days. Round \( t \) up to the nearest whole day. (c) \( P=(k \times 1000), i=2.2 \%, n=6 \). Find the amount of interest. (d) \( S=750, P=700, i=k \% \). Find the number of compounds rounded up to the nearest whole number. (e) \( S=4000, P=3500, n=(k \times 10) \). Find the periodic and nominal interest with monthly compounds. 2. (a) A bank account earns \( 1.5 \% \) simple interest for 1 year on a principal of \( \$ 1500 \). What amount does it grow to? ( (b) Another bank account also has a principal of \( \$ 1500 \) and grows to the same amount in (a) over the same amount of time. If this account has compound interest and gains interest each quarter, find the periodic interest rate. [ \( / 2 \) ] 2]
