HELP!!
Alekssandra [29.7K]

Answer: a) 25x+30y=221.25\\5x+45y=191.25

b) Cost of a macadamia nut chip cookie is $33.93 and the cost of triple chocolate cookie. is $3.77

c) Elimination method because it enables us to eliminate one of the variables.


Step-by-step explanation:

Let x be the cost of macadamia nut chip cookie and y be the cost of triple chocolate cookie.

Then according to the question we have the following equations:-

25x+30y=221.25..................(1)\\5x+45y=191.25.......................(2)

Multiplying 5 on both sides of the equation (2), we get

25x+225y=956.25...............(3)

By using elimination method, subtract equation (1) from (3) we get

195y=735\\\Rightarrow\ y=3.77

Substitute the value of y in (2), we get

5x+45(3.77)=191.25\\\Rightarrow\ 5x=191.25-169.65\\\Rightarrow\ x=33.93
