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
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. Be sure to show all your work.
2.
Describe how you would graph this line using the slope-intercept method. Be sure to write
using complete sentences.
3
Write the equation in function notation. Explain what the graph of the function represents. Be
sure to use complete sentences.
Graph the function. On the graph, make sure O label the intercepts. You may graph your
equation by hand on a piece of paper and scan your work or you may use graphing
technology.
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 a of at least three
complete sentences, explain how the graphs of the functions for the two months are similar
and how they are different.
