a. she will receive a refund of $278.

step-by-step explanation:

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

i'm using the rule log(x/y) = log(x) - log(y)

30.5*10=350$

you have to multiply the number without the decimal point then add it later but if its tenn u must move the place value of the decimal point 1 to the right.
