Answer:
10
Step-by-step explanation:
Let's call Ahmed's number x,
- If he multiplies it by 2, it becomes 2x
- He then divides it by 5 so it would be 2x ÷ 5
- The result was 4, so it would be written as 2x ÷ 5 = 4
To solve for x,
- First, multiply both sides by 5: 2x = 20
- Finally divide both sides by 2 to get x on its own: x = 10
- Answer: He was thinking of the number 10
You could also work backwards:
If he ×2 then ÷5, you would ×5 then ÷2 (doing the opposite):

Find the number of full ones by subtracting empty from total:
50 - 23 = 27 full
The ratio of empty to full is written as empty: full
Ratio = 23:27
Each adult ticket is 6$, so if you sell adult tickets you gain dollars.
Similarly, each student ticket is 2$, so if you sell adult tickets you gain dollars.
So, the total is
Since, in your case, a=90 and s=50, the expression becomes
N=15. Equation: You need to isolate N. Multiply both sides by 300 to get 300/20 = N. You can simplify it to 15.
