Answer:
1/2
Step-by-step explanation:
you can simply the fraction making it 1/2 and 1 - 1/2 = 1/2
The solution to the problem is as follows:
<span>→x− 4% (x) = 261</span>
<span><span>
→x − <span><span>4x/</span>100 </span>= 261

The answer is dividing stuff
Answer:
23%
Step-by-step explanation:
First, add all prices together
120.54 + 55.99 + 65.00 = 241.53
Then see what percent 241.53 is of 1,050
