Answer:[tex]A=\$150(1.05)^{t}[/tex]  Step-by-step explanation:we know that    The compound interest formula for this problem is equal to  [tex]A=P(1+r)^{t}[/tex]  where  A is the Final Investment Value  P is the Principal amount of money to be invested  r is the rate of interest  in decimalt is Number of Time Periods  in yearsin this problem we have  [tex]P=\$150\\ r=5\%=0.05[/tex]  substitute in the formula above  [tex]A=\$150(1+0.05)^{t}[/tex]  [tex]A=\$150(1.05)^{t}[/tex]
