Answer

a. 6321.2; b. $14068.1

Work Step by Step

a. $P=\int ^{10}_{0} 1000e^{-0.02t}.e^{-0.08t}=1000\frac{e^{-0.1t}}{-0.1}|^{10}_{0}=\frac{1000}{-0.1}(e^{-1}-1) \approx 6321.2 $ b. $A=e^{(0.08)10}\int^{10}_{0}1000e^{-0.02t}.e^{-0.08t}dt = e^{0.8}.1000\int^{10}_{0}e^{-0.1t}dt=e^{0.8}.1000.\frac{1}{-0.1}(e^{-0.1t}|^{10}_{0}) \approx 14068.1$
