Answer:
She will have to pay $375
Step-by-step explanation:
To calculate this you would first have to divide 500 by 4, which is 125. This is because the denominator is the total amount of 500. Then you would multiply 125 by 3, which is 375. This is because the numerator tells us how much of the denominator, and because the denominator is the whole amount and so by dividing you are finding out what 1 of those units is and then multiplying by the numerator that tells us how many of those units.
1) Divide 500 by 4.
2) Multiply 125 by 3.

Answer:
4² = 16
Step-by-step explanation:
The applicable rule of exponents is ...
1/a^-b = a^b
So, ...
_____
<em>Additional comment</em>
If you were to evaluate this using the Order of Operations, you would evaluate the exponent first:
1/4^-2 = 1/(1/16)
Then, you would do the division.
1/(1/16) = 16

We sometimes find it convenient to manipulate exponential terms to the form with the smallest positive exponents before we begin the evaluation.
