Answer: 2,000 milliliters.
Step-by-step explanation:
Hi, to answer this question we have to add the amount of water and the amount of sports drink that he drank:
1 liter + 1 liter = 2 liters of liquid.
Finally, we have to convert the result into milliliters.
Since 1 liter = 1000 liters
We have to multiply the liters drank by 1000.
2 x 1000 = 2,000 milliliters.
Feel free to ask for more if needed or if you did not understand something.
So you can do this by using a system of equations
x=student tickets
y=adult tickets
x+y=394
x+56=y
then you substitute y in
x+(x+56)=394
2x+56=394
2x=394-56
2x=338
x=169 which is the number of student tickets
then you find the amount of adult tickets
x+56=y
169+56=y
225=y
and now you can check it
225+169=394
394=394
Answer:
169 student tickets were sold
225 adult tickets were sold
The tip is $28
their total bill + tip = $165

Answer:
The simple interest accumulated on a principal of $ 2,500 at a rate of 6.25% per year for 2.5 years is $ 390.63.
Step-by-step explanation:
Given
- Interest rate r = 6.5% = 0.065
- Time period = t = 2.5 years
To determine
Interest I = ?
Using the simple interest formula
I = Prt
substituting P = 2,500, r = 0.065 and t = 2.5
I = 2500 × 0.0625 × 2.5
I = 390.63
Thus,
I = $390.63
Therefore, the simple interest accumulated on a principal of $ 2,500 at a rate of 6.25% per year for 2.5 years is $ 390.63.
