Answer:
[tex]22440=6200e^{0.06T}[/tex]
[tex]\implies \dfrac{561}{155}=e^{0.06T}[/tex]
[tex]\implies \ln\dfrac{561}{155}=\ln e^{0.06T}[/tex]
[tex]\implies \ln\dfrac{561}{155}=0.06T[/tex]
[tex]\implies T=\dfrac{50}{3}\ln\dfrac{561}{155}[/tex]
[tex]\implies T=21.43826314...[/tex]
[tex]22440=6200e^{0.1T}[/tex]
[tex]\implies \dfrac{561}{155}=e^{0.1T}[/tex]
[tex]\implies \ln\dfrac{561}{155}=\ln e^{0.1T}[/tex]
[tex]\implies \ln\dfrac{561}{155}=0.1T[/tex]
[tex]\implies T=10\ln\dfrac{561}{155}[/tex]
[tex]\implies T=12.86295789...[/tex]
