Step-by-step explanation:
Using proportions, it is found that she will pay $8.28 in total after the discount.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
Before tax, the total price is given by:
P = 3.59 + 4.25 + 3.99 = $11.83.
She gets a 30% discount, hence the proportion she pays is 70% of this amount, hence:
P = 0.7 x 11.83 = $8.28.
She will pay $8.28 in total after the discount.

Answer:
If log x = 2
x = 100
Step-by-step explanation:
Logarithm always has a base and an index. It can be I many forms.
It can be in base 2, 3, 4, 5, and so on.
It is a property of logarithm that if
logarithm of 'a' to base 'b' equals 'x', we write:
log_b (a) = x
Then,
a = b^x.
Usually, when a logarithm is written without a base, it tells us that it is in base 10. Instead of writing a logarithm of x to base 10,we can just write 'log x', it is sufficient to say that it is in base 10.
It can also be in the form of the Napierian Logarithm, 'ln'.
'ln x' is logarithm to base 'e'.
if ln x = 5
Then
x = e^5.
So,
log x = 2
Means logarithm of 'x' to base 10 equals 2.
x = 10^2
= 100
x = 100
