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 Nitide 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.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 of at least three complete
sentences, explain how the graphs of the functions for the two months are similar and how they
are different.

Given:

2x + 3y = 1470

convert to slope intercept form to find the slope and y-intercept.

In the slope intercept form: y = mx + bm is the slope and b is the y-intercept.

2x + 3y = 1470

3y = -2x + 1470

y = -2x/3 + 1470/3

y = -2x/3 + 490

slope is -2/3

y intercept is 490

2x + 3y = 1593

3y = -2x + 1593

y = -2x/3 + 1593/3

y = -2x/3 + 531

slope is -2/3

y intercept is 531

Both slopes are the same, the y-intercept increased by 41

If the trend is the same, I can assume that the third month will have this expression.

2x + 3y = 1716

2x + 3y = 1716

3y = -2x + 1716

y = -2x/3 + 1716/3

y = -2x/3 + 572

slope is -2/3

y intercept is 572.

I got the 1716 by multiplying 41 by 3 and adding the product to 1593.

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
