Answer:
Perimeter is equal to all four sides added together.
Length = 3W; L=3W
So
P = 2(W) + 2(L) substitute the equation for length above you get
P = 2(W) + 2(3W) and combine
P = 2W + 6W = 8W; put in what the perimeter is and solve for W
66 = 8W, so W = 8.25
W = 8.25, L = 24.75
After the music store he had $14 left, because 21:3=7 and 7x2 equals 14.
After the drink, he has $3.5 left, because 14:4=3.5 and 3.5x1=3.5.
Conclusion: that is one expensive drink. (Answer is 3 dollars and 50 cents. Hope this helped:)
