Answer:
Sal's Sandwich Shop sells wraps and sandwiches as part of its lunch specials. The profit on every sandwich is $2 and the profit on every wrap is $3. Sal made a profit of $1,470 from lunch specials last month. The equation 2x + 3y = 1,470 represents Sal's profits last month, where x is the number of sandwich lunch specials sold and y is the number of wrap lunch specials sold.
5. Suppose Sal's total profit on lunch specials for the next month is $1,593. The profit amounts are the same: $2 for each sandwich and $3 for each wrap. In a paragraph of at least three complete sentences, explain how the graphs of the functions for the two months are similar and how they are different.
6. Below is a graph that represents the total profits for a third month. Write the equation of the line that represents this graph. Show your work or explain how you determined the equations.

Step-by-step explanation:
14 + 5t > = 49 (thats a greater then or equal sign)
5t > = 49 - 14
5t > = 35
t > = 35/5
t > = 7 <===
Answer:
x=2
Step-by-step explanation:
Simplify both sides of the equation.
2x−1−(−x + 3)=6−2x
(Distribute the Negative Sign)
2x−1 + −1(−x + 3)=6−2x
2x + −1 + −1(−x) + (−1)(3)=6−2x
2x + −1 + x + −3=6−2x
2x + −1 + x + −3=6 + −2x
(Combine Like Terms)
(2x + x) + (−1 + −3)=−2x+6
3x + −4=−2x + 6
3x−4=−2x + 6
Add 2x to both sides.
3x−4 + 2x=−2x + 6 + 2x
5x−4=6
Add 4 to both sides.
5x−4 + 4=6 + 4
5x=10
Divide both sides by 5.
5x/5=10/5
x=2
Answer:
C. 8
Explanation:
One way to solve this is to find 30% of each class, 28 and 24.
30% of 28:
28 • 0.30 = 8.4
30% of 24:
24 • 0.30 = 7.2
You can then find the average of these two numbers.
8.4 + 7.2 = 15.6
15.6 ➗ 2 = 7.8
7.8 rounds up to 8
Another way to solve is to first find the average number of people in each class.
28 + 24 = 52
52 ➗ 2 = 26
You can then find 30% of this number.
26 • 0.30 = 7.8
7.8 rounds up to 8
