Answer:
Lourdes has $24.
Step-by-step explanation:
The appropriate equation would be L + (L/3) = $32, or 3L + L = $96.
Solving for L: 4L = $96, and L = $24. This is 3x what Ella has, so Ella has $8.
Check: Do $8 and $24 add up to $32? YES

Answer: 10y + 1
Step-by-step explanation:
The perimeter is the total distance round the figure.
Now, in this case it is going to be
Perimeter = 3y + 5 + 6y + y - 4
= 3y + 6y + y + 5 - 4
= 10y + 1
