Let h be the price of a hamburger, d be the price of a hot dog and c be the price of a cheeseburger
3+d=h —(1)
c-20=h —(2)
3h=2d+2c-75 —(3)

Sub (1), (2) into (3)
3h=2(h-3) + 2(h+20) -75
3h =2h-6+2h+40-75
3h=4h-41
h=41

Therefore, the price of a hamburger is $41

Answer:

2

Step-by-step explanation:

Linear equation form:  y = mx + b

(where m is the slope and b is the y-intercept)

The rate of change for a line is the slope.

Function 1:  y = 6

⇒ the slope is zero so the rate of change is zero

Function 2:  y = 2x + 7

⇒ the slope is 2 so the rate of change is 2

Therefore, 2 - 0 = 2

So the rate of change of function 2 is 2 more than the rate of change of function 1
