m = t2.5
So money equals to tickets sold*2.5
2.5 is each tickets price
If you ask how I found;
$100 / 40 tickets = $2.5
Answer: 
=====================================
Work Shown:
6x-y = -3 is the same as 6x-y+3 = 0
6x-y+3 = 0 is the form Ax+By+C = 0 with A = 6, B = -1, C = 3.
The distance d that line is from the point (p,q) = (6, 2) is found by the following

Answer:
1- solve for x
2- put it in the bottom left square
Step-by-step explanation:
Actually you have 2 coefficients here: 3/8 and 3/4.
(3/8)d + (3/4) is the same as (3/8)d + (2)(3/8), so this can be factored into
(3/8) [ d + 2 ]
