Step-by-step explanation:
Answer: r=7.4%=0.074
Move decimal over two places
P=13000
Given as the principal
t=19
Given as the time
V=Pe^{rt}
V=13000e^{0.074( 19)}
Plug in
V=13000e^{1.406}
Multiply
V=53034.856≈53034.86
Use calculator and round to nearest cent
Let x be the yearly salary of an architect. Then the yearly salary of a lawyer is 2x-20000.
We can build an equation now! x+(2x-20000)=211000, because the yearly salary of an architect plus the yearly salary of a lawyer is 211000.
We combine like terms to get 3x-20000=211000.
We add 20000 to both sides to get 3x=231000.
We divide both sides by 3 to get x=77000, so the average yearly salary of a lawyer is 77000.
Then, the average yearly salary of an architect is 2(77000)-20000=154000-20000=134000, so the average yearly salary of an architect is 134000.
