Answer:  a) $135,838.21           b) $46,130.05
<u>Step-by-step explanation:</u>

- A: accrued amount (balance)
- P: principal (initial amount invested)
- r: interest rate (in decimal form)
- t: time 
 (a) Given:
- A = 400,000
- P = unknown
- r = 12% = 0.12
- t = 9

 (b) Given:
- A = 400,000
- P = unknown
- r = 12% = 0.12
- t = 18

So with the problem the equation for answering these would be “1.50t+4=c” so to plug in the variable for t would be 0, 1, 2, 3, etc. and the variable c would be the answer of solving the equation with the plugged in number
1.50(0)+4= $4.00
1.50(1)+4= $5.50
1.50(2)+4= $7.00
1.50(3)+4= $8.50
