Answer:
There were 150 student tickets and 200 adult tickets sold
Step-by-step explanation:
Let s and a represent the numbers of student and adult tickets sold, respectively. Then the two equations are ...
s + a = 350 . . . . . . total number of tickets sold
12.50s + 16.00a = 5075 . . . . . .total value of tickets sold
___
<u>Solution</u>
The first equation lets us write an expression for s:
s = 350 - a
We can substitute this into the second equation:
12.50(350 -a) +16.00a = 5075
3.50a + 4375 = 5075 . . . . . . . . . simplify
3.50a = 700 . . . . . . . . . . . . . . . . . subtract 4375
a = 200 . . . . . . . . . . . . . . . . . . . . . divide by 3.50
There were 200 adult tickets and 150 student tickets sold.
Density is a physical property which describes the mass of a substance per unit of volume of the substance. It is expressed as Density = m / V and it has units like g/cm^3. We use the density given to solve the problem.
Volume of the tank = 8 fishes / 0.2 fish / ft³
The volume of the tank = 40 ft³
Answer:
