I believe 3.7 is your answer
Answer:
36.73%
Step-by-step explanation:
Let x = 100
13% increase = 100(1 + 0.13) = 100 + 13 = 113
21% increase = 113(1 + 0.21) = 113 + 23.73 = 136.73
Hence, a single percentage to arrive at 136.73 will be :
x
100(1 + x) = 136.73
100 + 100x = 136.73
100x = 136.73 - 100
100x = 36.73
x = 36.73 / 100
x = 0.3673
0.3673 * 100% = 36.73%
Answer:

Step-by-step explanation:
Answer:
Yes
Step-by-step explanation:
You can estimate 1/5 to 1/4 and 4/8 to 2/4 Therefore 1/4+2/4 is 3/4
The number is in between 20 and 28, but is not divisible by 2, 3, 4, or 5. So, 20, 22, 24, 26, 28 are removed because it is divisible by 2. We can remove 21 and 27 because those numbers are divisible by 3. So now we have 23 and 25 remaining. But 25 is divisible by 5, so the number of students in the chess club is 23. Your answer is 23.
