The perimeter is equal to 2 * width + 2 * length. We are provided that the width is 3 feet and the perimeter is 10 feet. So, 2 * 3 + 2 * length = 10 6 + 2 * length = 10 2 * length = 4 length = 2
The answer is 2 because if 2 sides are 3, then you add 3+3 which is 6. Then you think what plus 6 equals 10 which is 4. Finally, you have to take 4 and split it in half which is 2. Your answer is 2.
Let X = be the amount the amount that new customer will have to pay
X = 0.8P + 100
