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. 1. Change the equation to slope-intercept form. Identify the slope and y-intercept of the equation.
2. Describe how you would graph this line using the slope-intercept method.
3. Write the equation in function notation. Explain what the graph of the function represents.
4. Graph the function. On the graph, make sure to label the intercepts.
5. Suppose Sal’s total profit on lunch specials for 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 are they different.
