A. The equation: 21.25 - 12.50 which is loran’s team = 8.75.
B. No Dario wouldn’t be correct, because the price of loran’s shirt - bens team= 8.75 which means Ben is on team C and not B!
If the sides are proportional you can use the formula:
3x + 4x + 5x = 240 and solve for x.
which is: 12x = 240
x = 20
The longest side is 5x, so the longest side is 100.
