Answer:
b
Step-by-step explanation:
First, you have to set up two equations.
X + y = 45
18x + 24y = 1,050
To do this, you have to solve for an exponent by cancelling out the other one. To solve for y, you multiply everything in the first equation by -18.
-18x -18y = -810
This cancels out the x and leaves you with 6y = 240. Divide both sides by 6 and you have the number of Yankee hats that were bought.
Then, you have to substitute 40 for y in the first equation and solve for x.

Answer:
w = -y + 1/3 + 1/3x
Step-by-step explanation:
Step 1: Distribute
x = 3y + 3w - 1
Step 2: Switch <em>x</em> and <em>w</em>
-3w = 3y - x - 1
Step 3: Divide everything by -3
w = -y + x/3 + 1/3
(22a) 1500 x 1.6 x 2
(22b) DEV 1500 x 1.8=2700 1500 x 1.3=1950 2700+1950=4650 1500 x 1.6 x 2= 4800 4650(Emma) < 4800(Dev)
I strongly suggest to check my work. Good Luck and hoped I helped at least a little (I am very tired and it was almost midnight when I did this sorry for any errors).
