We can solve this by using systems of equations.
Let's find our first formula, how much money was made using the tickets.
Here x is how many child tickets we sold and y is how many adult tickets we sold. Now that we have defined that, we can make another formula for the total tickets sold!
since we sold 156 tickets that could be any combination of child and adult tickets.
Let's solve this system. I'm going to use <em>substitution</em> so I'm going to take our second formula and subtract both sides by x to get 
.
Now I will plug this in the first equation for y to get You plug it in for y to get 
From this you can solve for x to get 
.
Since 
There were 99 child tickets and 57 adult tickets.
So Katelyn bought 5.68 pounds of peaches. And one pound of peaches cost $1.49. So that would mean that we would have to multiply the pounds of peaches she bought, with how much each pound costs. 5.68 × 1.49 = ?
Once you multiply these two decimals, you would get 8.4632. So she spent $8.4632 on 5.68 pounds of peaches. You would multiply the two decimals to find how much she spent in all.

Step-by-step explanation:
Volume of a cylinder is just the area of the circle-surface multiplied by the height of the cylinder.
We're given that the radius=8 and height=56
