Question

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. Write the equation in function notation. Explain what the graph of the function represents.

Answer 1

Best way I can explain it is $2 for X, X is amount of sandwiches she sold, $3 for every Y, Y is the amount of wraps she sold, 1 month she made $1,470

therefor 2x + 3y = 1,470

Answer 2

Answer:

f(x)= -2/3x+490

Step-by-step explanation:

In the function notation this would be f(x)= -2/3x+490. The function shows how the profit of wrap specials change as the number of the sandwich specials sold increases. The next month when Sal's profit increases the function changes because the y-intercept changes. the slope however does not change
