400=220(1.03)^t
1.8181=1.03^t
ln 1.8181=ln 1.03^t=t ln 1.03
ln 1.8181/ln 1.03=t
t=20.225 years

Answer:
x= 1 when y =4 , x= 5 when y = 8 , x=2 when y = 5.
Step-by-step explanation:
y=x+3
Through this rule we have to find out the values of x when values of y are given:
y=x+3
y = 4
Substitute the value in the rule:
4=x+3
Combine the constants:
4-3=x
x= 1 when y =4
y=x+3
y = 8
8= x+3
Combine the constants:
8-3= x
5=x
x= 5 when y = 8
y=x+3
y = 5
5=x+3
Combine the constants:
5-3=x
2=x
x=2 when y = 5....
