Answer:
The number of sandwiches sold is 73. This is because it is multiplied by the expression for the money received per sandwich.
The cost to make each sandwich is <em>S. </em>This is stated in the first sentence of the problem.
<em />
The profit is 0.2<em>S. </em>This is because they sell each sandwich for an additional 20% of the cost ( S )
<em />
The amount of money the band receives is (<em>S </em>+ 0.2<em>S </em>). This is because it is the price per sandwich.

2 4/9 is the correct answer*
Let see...
So we know that × is less than 14.3 subtract by 9.
We can figure out what × is is by subtracting 14.3 with 9 and then find the answer less than it.
So now we know that the answer can be 5.3 or more. This means that we can cross out 5.3, 6.4, and 7.5.
So it would be 3.1 and 4.2.
Answer:
w = I /2 - 4
Step-by-step explanation:
half the length : I /2
4 less than half the length : I /2 - 4
To match the requirements : w= I /2 - 4
We have a system of equations 2x - 4y = 5 and 6x - 3y = 10.
We want to eliminate one variable when we add up the equations.
If we want to eliminate the x variable, we need to multiply the top, bottom or both of the equations with a number that when the equations are added together will eliminate the x variable.
Multiply the top equation by -3.
-3(2x - 4y) = 5 * -3
-6x + 12y = -15
Now when we add the two equations together, the x's will be eliminated.
-6x + 12y = -15
6x + 6y = 10
18y = -5
The x's were eliminated.
