It costs $122.4 dollars before the increase.

<h3>How to calculate percentage of a number. Use the percentage formula: P% * X = Y</h3>
  • Convert the problem to an equation using the percentage formula: P% * X = Y.
  • P is 17%, X is 7.20, so the equation is 17% * 7.20 = Y.
  • Convert 10% to a decimal by removing the percent sign and dividing by 100: 10/100 = 0.10.

Therefore, It costs $122.4 dollars before the increase.

Solve the quadratic equation x2 - x = 30 by completing the square
kap26 [50]

Answer:

A

Step-by-step explanation:

Given

x² - x = 30

To complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(- \frac{1}{2})x + \frac{1}{4} = 30 + \frac{1}{4}

(x - \frac{1}{2})² = \frac{121}{4}

Take the square root of both sides

x - \frac{1}{2} = ± \sqrt{\frac{121}{4} } = ± \frac{11}{2}

Add \frac{1}{2} to both sides

x = \frac{1}{2} ± \frac{11}{2}, thus

x = \frac{1}{2} - \frac{11}{2} = - 5

x = \frac{1}{2} + \frac{11}{2} = 6
