Answer:
See below.
Step-by-step explanation:
(a) Let the cost of the macadamia dough = x and cost of the triple chocolate dough = y.
So we have the following system of equations:
25x + 30y = 221.25 ( Juliens class)
5x + 45y = 191.25 ( Castilejo's class). (Answer).
(b)
Solving:
25x + 30y = 221.25 ......... (1)
5x + 45y = 191.25 ..............(2)
Multiply equation (2) by -5:
-25x - 225y = -956.25 .... (3)
Now add equations (1) and (3):-
-195y = -735
y = $3.77
Substituting in equation (1)
25x + 30(3.77) = 221.25
25x = 221.25 - 113.08 = 108.17
x = $4.33.
Answer The macadamia dough costs $4.33 and the chocolate cost $3.77.
(c) I used the elimination method to solve this because the substitution method would be more awkward - it would involve more calculation and higher numbers.
Divide the funny looking shape into many simple common figures and find the area of the common figures. Then add the areas of the figures to find the total area of the funny looking shape.

Answer:
999.60
Step-by-step explanation:
1 month is about 4 week
so 1 week=3998.40/4=999.60$
This equation means that you mustfind the height which in this case is W. ok in order to find w you must do the opposite equation to the output so divide 183 by 212 and the answer is W so W=.9 ( im only in 9th grade so this may or may not be correct)
