The answer is A). 20% is equal to 1/5. So 20*5=100, so you be able to divide it by 2 and get 50. From there you would find how much money is spent.

5x-3 = 4x/3 +4
5x - 4x/3 = 7
(11/3)x = 7
x = 7/(11/3) = 21/11

<h3>Answer: Choice C</h3>

The base 16 is the same as 4*4.

From there, the rule $(a*b)^c = a^c*b^c$ is used to get $(4*4)^{1/2} = 4^{1/2}*4^{1/2}$

Afterward, the exponents are added getting 1/2+1/2 = 2/2 = 1. The rule is $a^b*a^c = a^{b+c}$ which only works if the bases are both the same.
