Answer:
Step-by-step explanation:
Start by representing the lengths of the three sides of your triangle:
first side: x-4 (inches)
second side: x (inches)
third side: (x-4) + 3 (inches)
Add these three quantities up to obtain a formula for the perimeter, and set your sum equal to the given perimeter (15 inches):
x-4 + x + x-4 -3 = 15
3x-11=15
3x=26
x=26/3
Thus, the length of the 2nd side is 26/3; that of the first side is 26/3-4, or 14/3; and that of the third side is 14/3+3, or 23/3 (all measurements in inches).
First, you need to find the total amount they discounted.
3.66 X 3= $10.97
Since they took off that much, you need to add that to the total cost, which was 62. 31
62.31 + 10.97= $73.29
Finally, to find how much each individual shirt cost, you divided it by 3.
73.29 / 3= $24. 43
The answer is C
