Answer:
we can do it by simplifying 8 to
to make both powers base two, and subtracting the exponents.
Step-by-step explanation:
We have been given the expression 
8 can be rewritten as 
Hence, the given expression becomes

After subtracting the exponents on left hand side of the equation we get:

we can do it by simplifying 8 to
to make both powers base two, and subtracting the exponents.
The given equations are
12x + 4y = 152 ...........1
32x + 12y = 420 .....2
Multiplying equation 1 by 3 to make coefficient of y same we have:
36x+12y= 456
32x+12y=420
Subtracting the two equations we have:
4x=36.
Dividing by 4 both sides
x= 9.
Substituting x value in equation 1
12(9) + 4y = 152
108+4y=152
Subtracting 108 both sides: 4y=44.
Dividing both sides by 4.
y=11.
cost of the vegetarian lunch is $11.
In the equations, x represents the cost of a chicken lunch and y represents the cost of a vegetarian lunch.
