The rule we use here is 
If the font size is too small, then it says (a^b)/(a^c) = a^(b-c)
We subtract the exponents when dividing exponentials like this. The bases must be the same.
So this means the exponents 13 and 3 subtract to get 13-3 = 10
We either have an exponent of "13-3" or an exponent of "10" as an equivalent expression. The base stays at 2 the entire time.
Answer:

Answer:
$18
Step-by-step explanation:
The initial price is $25
When the first 10% is off, the new amount is (100 - 10)% x 25
= 0.9 x 25
= 22.5
With an additional 20%
the new amount is (100 - 20)% x 22.5
= 0.8 x 22.5
= $18
