Answer:

1,400(1.1)^.5t

Step-by-step explanation:

semianually means half a year. you can represent this as .5t.

1.1 is the interest she earns 1400+(percentage she earns)

Goldenpoo21idn
P=1400
r=10%=0.10 as a decimal
n=2

Form the problem
y=1400(1+0.10/2)^2t=1400(1.05)^2t

Now we substitute the solution in the variables given which are P,r,n so that we can create our own interest formula

y=P(1+r/n)^nt

y=1400(1.05)^2t

Therefore the answer of the 1400 deposit that earns 10% for the annual interest compound semiannually would be y=1400(1.05)^2t
