Answer:
230 * (30/100) = 23 * 3 = 69
Step-by-step explanation:
This one can be learned by heart: "what is 30% of 230" means "calculate 30/100 times 230".
Let x represent the number of half-gallons purchased by the store. Then x-13 is the number sold, and 2.80x is the store's cost. The revenue is 4.06(x-13) and the difference between that and cost is the profit.
... 4.06(x -13) -2.80x = 63.14
... 1.26x - 52.78 = 63.14 . . . . eliminate parentheses, collect terms
... 1.26x = 115.92 . . . . . . . . . . add 52.78
... x = 115.92/1.26 = 92 . . . . . divide by the coefficient of x
The store purchased 92 half-gallons of milk.
One simple approach would be to choose an x value, such as x = 8, calculate y using the given formula, and then choosing the graph that shows a C(t) value closer to your calculated value.
Please evaluate C(8).

Volume of a Cuboid Formula: V = a²h
- <em>a</em> is the sides of the cube
- <em>h</em> is the height
Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify variables</em>
<em>a</em> = 3
<em>h</em> = <em>h</em>
<em />
<u>Step 2: Find Volume</u>
- Substitute in variables [Volume of a Cuboid Formula]: V = 3²h
- Evaluate exponents: V = 9h
