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
