138000 + 23391 = 161391
Multiply it out and collect terms.
y = (x - 3)² + 36
y = (x² -6x +9) +36
y = x² -6x +45
Answer:
B=62, a=3.7, C=7.9
Step-by-step explanation:
We use x to represent the price of the cheapest hat. Since the more expensive hat is twice the price of the cheaper one, we use 2x to represent it. Therefore x + 2x, or 3x, equals $75.12. Divide 75.12 by 3 to find x, which is 25.04. The more expensive hat is 2x, so we must multiply 25.04 by 2 to find the price of the more expensive hat. Therefore, the cost is $50.08.
