Question #1
1. sal’s sandwich shop sells wraps and sandwiches as part of its lunch special. the profit on each sandwich is $3 and the profit on each wrap is $4. the company made a profit of $1,680 from lunch specials last month. the equation in standard form, ax + by = c, 3x + 4y = 1680, represents the company’s profit from last month from x number of sandwiches and y number of wraps.

x represents the number of what? sandwiches or wraps (circle one)
y represents the number of what? sandwiches or wraps (circle one)

change the equation into slope intercept form, y = mx + b. identify the slope and the y-intercept.
show your work below:

Step-by-step explanation:

This is a reading comprehension question. The problem statement tells you ...

  "x number of sandwiches" and "y number of wraps."

You should be able to deduce that ...

  x represents the number of sandwiches

  y represents the number of wraps

___

The equation 3x+4y=1680 is put into slope-intercept form by solving for y.

  4y = -3x +1680 . . . . . subtract 3x

  y = (-3/4)x + 420 . . . .divide by 4

Comparing this to the slope-intercept form y = mx + b, where m is the slope and b is the y-intercept, we see that ...

  y-intercept = 420

  m = -3/4

9x

12r - 8 - 12

you have to combine like terms. below i have bolded the like terms:

12r - 8 - 12

together it combines to:

12r - 20

hope this !
