ANSWER

B.

[tex]A=4.25(1.10)^t[/tex]

EXPLANATION

The formula for calculating the cost in t years is given by:

[tex]A=C(1+r)^t[/tex]

To determine the cost in t years for a gallon of milk, we substitute,

C=$4.25

and

r=10%=0.10

in to the above formula to obtain:

[tex]A=4.25(1+0.10)^t[/tex]

Simplify the parenthesis to get,

[tex]A=4.25(1.10)^t[/tex]

The correct choice is B.
